Description of problem:
If I try to use the Pod::Man "parse_file" function, I get failures.  Even the simplest invocation, directly from the man page, gives uninitialized value and strict refs errors.

Version-Release number of selected component (if applicable):
$ rpm -qf /usr/share/perl5/Pod/Man.pm
perl-5.10.1-119.el6_1.1.x86_64

The documentation (man Pod::Man) says:

    SYNOPSIS
           use Pod::Man;
           my $parser = Pod::Man->new (release => $VERSION, section => 8);

           # Read POD from STDIN and write to STDOUT.
           $parser->parse_file (\*STDIN);
    ...
       The standard Pod::Simple method parse_file() takes one argument naming
       the POD file to read from.  By default, the output is sent to "STDOUT",
       but this can be changed with the output_fd() method.


How reproducible:
100%

Steps to Reproduce:
Run this at a shell prompt:

$ perl -e 'use Pod::Man; my $p = Pod::Man->new(); $p->parse_file($ARGV[0]);' /usr/share/perl5/Pod/Man.pm

OR:

$ perl -e 'use Pod::Man; my $p = Pod::Man->new(); $p->parse_file(\*STDIN);' < /usr/share/perl5/Pod/Man.pm

  
Actual results:

$ perl -e 'use Pod::Man; my $p = Pod::Man->new(); $p->parse_file($ARGV[0]);' /usr/share/perl5/Pod/Man.pm
Can't use string ("") as a symbol ref while "strict refs" in use at /usr/share/perl5/Pod/Man.pm line 722.


Or if you add use strict:

$ perl -we 'use strict; use Pod::Man; my $p = Pod::Man->new(); $p->parse_file($ARGV[0]);' /usr/share/perl5/Pod/Man.pm
Use of uninitialized value in ref-to-glob cast at /usr/share/perl5/Pod/Man.pm line 722.
Can't use string ("") as a symbol ref while "strict refs" in use at /usr/share/perl5/Pod/Man.pm line 722.


Expected results:
I expect the output to go to STDOUT in nroff format.

Additional info:
The parse_from_file() method does appear to work correctly.
