Description Alex Jia 2010-09-08 08:26:49 UTC 
Description of problem:
Ruby-libs depends on old libreadline.so.5 share library, but readline package provides new libreadline.so.6 in RHEL6.0 RC, so we can't successfully install ruby-libs package, finally, I can't also successfully install ruby.

Version-Release number of selected component (if applicable):
# uname -a
Linux dhcp-66-92-184.nay.redhat.com 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1

How reproducible:

Steps to Reproduce:
# cd /media/RHEL_6.0\ x86_64\ Disc\ 1/Packages/

# rpm -qRp ruby-1.8.7.299-4.el6.x86_64.rpm | grep ruby-libs
ruby-libs = 1.8.7.299-4.el6

# rpm -qRp ruby-libs-1.8.7.299-4.el6.x86_64.rpm | grep libreadline
libreadline.so.5()(64bit)  

# rpm -q readline
readline-6.0-3.el6.x86_64

# rpm -ql readline-6.0-3.el6.x86_64 | grep libreadline
/lib64/libreadline.so.6
/lib64/libreadline.so.6.0

  
Actual results:
# rpm -ivh ruby-libs-1.8.7.299-4.el6.x86_64.rpm
error: Failed dependencies:
	libreadline.so.5()(64bit) is needed by ruby-libs-1.8.7.299-4.el6.x86_64


Expected results:
Resolve ruby-libs package dependant relationship

Thanks for the report.
We'll have to reconcile that with the following from ruby.spec:

   * Thu Jul 23 2009 Mamoru Tasaka <mtasaka.u-tokyo.ac.jp> - 1.8.6.369-2
   - Make sure that readline.so is linked against readline 5 because
     Ruby is under GPLv2
Comment 3 Jim Meyering 2010-09-10 14:02:45 UTC 
FYI, there's significant discussion on this topic here:

    http://redmine.ruby-lang.org/issues/show/2032
Comment 4 Jim Meyering 2010-09-20 06:01:59 UTC 
That was resolved (in 1.9 at least) on Sept 16, 2010 by ruby's license change
http://redmine.ruby-lang.org/repositories/revision/ruby-19?rev=29262

    from a dual license with GPLv2
    to a dual license with 2-clause BSDL.

which *is* listed as being GPL-compatible:

    http://www.gnu.org/licenses/license-list.html

Currently, COPYING on the ruby_1_8_7 branch has not been updated.
Comment 7 Mamoru TASAKA 2011-01-27 16:24:27 UTC 
From this:
http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-8-7-p330-released/
the upstream seem to be saying that they won't change the license
of ruby 1.8.7.x, so ruby in RHEL6 should still use readline 5.
Comment 8 Vít Ondruch 2011-02-01 15:17:09 UTC 
1) Thank you Mamoru, apparently you are right. I'm going to revert back to readline5.

2) It seems to me that bug is misunderstanding. While it is true that Ruby depends on readline 5, it is also true that all dependencies are satisfied. It is necessary to install compat-readline5 package instead of readline. Yum can solve these dependencies for you.
