Description Andrew Kornak 2007-10-16 23:13:17 UTC 
Description of problem:
While attempting to install a perl module a disrepancy was found in the perl
build on Fedora 7. 

Version-Release number of selected component (if applicable):
perl-5.8.8-24.fc7.i386

How reproducible:
Attempt to install the Task::Weaken perl module and an error will be produced.

Steps to Reproduce:
1. perl -MCPAN -e "install Task::Weaken"
2. Scalar::Util::weaken  ERROR
3.
  
Actual results:

 ERROR:

    A CPAN module critically requires a function
    (Scalar::Util::weaken) that should exist in your
    Scalar::Util module but doesn't.

    This probably happened because you are using a Perl
    provided by a binary package from a vendor, and this
    vendor has packaged Perl incorrectly.

Expected results: 

Module is installed.


Additional info:
Comment 1 Andrew Kornak 2007-10-16 23:18:42 UTC 
In addition to the above problem, since the latest perl update, I cannot install
any perl modules. The following error is thrown:

Undefined subroutine &Compress::Zlib::gzopen called at
/usr/lib/perl5/5.8.8/CPAN.pm line 5721

I am not sure if this is related or not. Something happened in the last build.
Comment 2 Andrew Kornak 2007-11-03 00:17:25 UTC 
The solution to the buggy perl builds are to manually re-install Scalar::Util.

Unfortunatley, the latest perl build has the same problem and I had to manually
re-install.
Comment 3 Andrew Kornak 2007-11-13 13:56:46 UTC 
Latest perl update has the same problem:

perl-5.8.8-26.fc7

Manually re-install Scalar::Util to get around the problem.
Comment 4 Tom "spot" Callaway 2007-11-13 15:26:22 UTC 
I'm not sure where this bug arises from. The Fedora perl package contains
Scalar::Util, with the weaken function.

I tested it like this:

[SHOULD FAIL]
perl -e 'use Scalar::Util qw(foo)'

[spot@localhost ~]$ perl -e 'use Scalar::Util qw(foo)'
"foo" is not exported by the Scalar::Util module
Can't continue after import errors at -e line 1
BEGIN failed--compilation aborted at -e line 1.

[SHOULD NOT FAIL]
perl -e 'use Scalar::Util qw(weaken)'
[spot@localhost ~]$ perl -e 'use Scalar::Util qw(weaken)'
[spot@localhost ~]$

Just to double check, I downloaded Task-Weaken-1.01.tar.gz from CPAN, and was
able to successfully build/install it without errors on F-7.

My best guess is that you have a mismatch of perl, some locally built or older,
and Fedora's perl, but I can't reproduce this on a clean F-7 build.
Comment 5 Andrew Kornak 2007-12-05 07:24:58 UTC 
After making the perl update, the same problem recurred...

==========================

There is an issue with the Fedora perl builds that cause this issue. 

Any attempts to install a module will fail.. another example:


> cpan Catalyst::Plugin::ConfigLoader

...

#   in t/21-mock_load_env.t at line 9.

In addition, after manually re-installing Scalar::Util, this problem is fized...

Also, I get the following error message when installing DBIx modules which may
or may not be related...

cpan Catalyst::Authentication::Store::DBIx::Class ...

WARNING: DBIx::Class::StartupCheck: This version of Perl is likely to exhibit
extremely slow performance for certain critical operations.
Please consider recompiling Perl.  For more information, see

You can suppress this message by setting DBIC_NO_WARN_BAD_PERL=1 in your
environment.

> After making the perl update, the same problem recurred...

My guess is still that you have a locally compiled copy of perl, and cpan built
addon modules against that locally compiled copy.

When you update to the Fedora perl, the two environments get confused again, and
you get all these failure cases.

This is made even more evident by your last comment, about bz 196836, which is
definitely fixed in the F-7 perl.

Look at 245592 (and 294021). You almost certainly have locally compiled bits in
site_perl which are to blame, not the Fedora packaged bits. Closing this as NOTABUG.

To be wholly fair, if you can tell me how to reproduce this, literally, step by
step, with step 1 being a clean install of Fedora on a system (or in a virtual
machine), with the explicit commands (cpan calls, yum calls, etc) which can get
the clean Fedora 7 system in this state, I will be happy to troubleshoot the
reproduced issue, but I have been entirely unable to reproduce your problems on
a clean system.

I really thought I did that in the previous steps. I do not have a locally
compiled version of perl. It is purely Fedora built. I am not that adventurous.
I just install various modules from cpan that are not built in to fedora.  

Step 1. yum update (installed latest perl updates)
Step 2, cpan "module with Weak references requirment or in my case any cpan module
Step 3. failed install with various errors depending on module:
        "Undefined subroutine &Compress::Zlib::gzopen" or
        "Error:  Weak references are not implemented in this version of perl"
Step 4. Install Scalar::Util (Scalar-List-Utils)
Step 5. cpan "any module" works fine now.

The previous errors occur each time a perl update happens. I am lost as to what
else the problem could be beyond the fedora perl build.
