themoops has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I had a problem with a module, so I go to cpan

So I type "i File::Path"

and I get this: 

CPAN: Storable loaded ok
Going to read /root/.cpan/Metadata
  Database was generated on Mon, 09 Apr 2012 17:10:35 GMT
Going to read /root/.cpan/sources/authors/01mailrc.txt.gz
CPAN: Compress::Zlib loaded ok
Undefined subroutine &IO::Uncompress::Base::readonly called at /usr/li
+b/perl5/site_perl/5.8.8/IO/Uncompress/Base.pm line 1075.

[download]

This is on centos 5, I did some updates, and it seems to have screwed some perl stuff up.

Any ideas what's wrong? Thanks.

    IO::Uncompress::Base is core and was first released with perl-5.9.4. If your version is less than that, then you'll have to install it. In the CPAN shell: 
    cpan> install Bundle::Compress::Zlib

    [download]
    or as a last resort: 
    cpan> install Bundle::Compress::Zlib IO::Uncompress::Base

    Hi themoops

    I also faced same issue today and just solved it.

    issue is with Scalar::Util perl module. Looks like CentOS update installs older version of Scalar::Util module. So perl could not load this module.

    To Solve this issue,

      Download Scalar::Utils sources from http://search.cpan.org/~pevans/Scalar-List-Utils-1.25/lib/Scalar/Util.pm
      1. extract .tar.gz file and cd Scalar-List-Utils-1.25
      2. perl Makefile.PL
      3. gmake
      4. gmake test
      5. gmake install


      Once you complete this successfully, 
       perl -MCPAN -e 'shell'

      [download]
      works fine and I could install modules.

      Thanks & Regards,

      Spot on Bakkiaraj, thanks!

      I was receiving the following error when attempting to execute some code, and your solution resolved the situation. BTW I'm running RHEL - 2.6.18-238.19.1.el5. 
      List::Util object version 1.21 does not match bootstrap parameter 1.25
+ at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/XSLoader.pm line

      Your message probably saved me hundreds of dollars in customer orders that would have been lost because my scripts started breaking after yum reinstalled Perl 5.8.8 overnight on my CentOS managed cloud server. Rackspace Support helped me scope out the problem, and we found your message on Google. It provided the exact solution to the problem.

      THANK YOU!

      Bakkiaraj, Thank you for the post. That saved me a lot of time. How did you figure out that this problem:

      was caused by a bad Scalar::Util module ?

        The version number in that link has increased. Either use a Google search to find the current URL or use the [dist://] form of URLs to create a link to whatever version is current, like Scalar::List::Utils.

    According to corelist, File::Path is part of the Core distribution, which means there should be no need to install it: 
    corelist File::Path

File::Path was first released with perl 5.001

    You will need to download at a different location now... http://search.cpan.org/dist/Scalar-List-Utils/ This fixed my issues... KD.

      Thanks so much. Peer1 updated my server again (I asked them to just email me so I can do it manually), and a bunch of my perl scripts crashed. This fixed it immediately!

    This worked on RedHat 5 (Linux <snip> 2.6.18-308.16.1.el5 #1 SMP. CPAN broke after a yum update. Your fix resolved the issue. Thank you!
