If you find that yours is occupying too much disk space, delete it, and run the following commands:

perl -MCPAN -e shell

cpan> install Bundle::CPAN>
cpan> reload index
cpan> reload cpan
cpan> exit

/scripts/checkperlmodules –full

Most common Perl modules can be installed from WHM ~> Install a Perl Module, or from command line. If you don’t know the name of the Perl module you’re installing, you may want to use the WHM installer instead, as it has a search feature and its usage is pretty self-explanatory.

For command line installations, pass the name of the perl module (case-sensitive) to the installer like so:

/scripts/perlinstaller MD5

/scripts/perlinstaller IO::Compress::Base

If the module is already installed and you need to update or reinstall it, pass –force:

/scripts/perlinstaller –force MD5

Since cPanel 11, you can now also allow your users to install their own perl modules locally in /home/$user/perl (which is automatically added to their Perl module path) so they don’t have to bug you when they need a Perl module, nor to they need SSH access.  You can enable this in WHM ~> Module Installers ~> Perl Module [Manage] . You do need to have compilers enabled for users though, which can be done in WHM ~> Security Center ~> Compilers Tweak .

How do I know it’s broken?

It’s usually pretty obvious, but when you get error every time you open cPanel or WHM, or get perl errors when you try to run any of the scripts in /scripts, accompanied by a slew of errors in the cPanel error log (/usr/local/cpanel/logs/error_log), it’s clear that cPanel and/or Perl is malfunctioning.

The good thing is, cPanel and Perl can usually be fixed rather easily.

First things first, if you’re just getting a simple Perl error, you may just be missing a couple Perl modules. Take for example an error that looks like this:


Can't locate IPC/Open3.pm in @INC (@INC contains: /scripts /usr/local/cpanel /usr/local/lib/perl5/5.8.8/x86_64-linux /usr/local/lib/perl5/5.8.8 /usr/local/lib/perl5/site_perl/5.8.8/x86_64-linux /usr/local/lib/perl5/site_perl/5.8.8 /usr/local/lib/perl5/site_perl .) at /scripts/pkgacct line 22.
BEGIN failed--compilation aborted at /scripts/pkgacct line 22.


This references a Perl module that does not exist, in which case you can just install it. The name of the Perl module is indicated in the error, just replace the slash with double-colons and pass it through /scripts/perlinstaller :

/scripts/perlinstaller IPC::Open3

If that fixes the problem, great…you may have to do this a couple more times for other perl modules. But you know there’s a REAL problem when the Perl installer fails, or the perl module is made by cPanel and doesn’t exist in the standard CPAN repos. In that case, you may need to resync the cPanel scripts.

First, run the following command to get your cPanel version branch:

cat /usr/local/cpanel/version

This should return something like 11.24.5-STABLE_38506, indicating that the branch is STABLE. Other branches indicated could be RELEASE, CURRENT, BETA, or EDGE. Use this branch to download the scripts folder from the cPanel repo. The below example is for STABLE:

wget -O scripts.tar.bz2 http://httpupdate.cpanel.net/cpanelsync/STABLE/scripts.tar.bz2
tar -xvC / -j -p -f scripts.tar.bz2
chmod 755 /scripts/cpanelsync
/scripts/cpanelsync httpupdate.cpanel.net /cpanelsync/STABLE/scripts /scripts
/scripts/upcp –force

Problem still not fixed? Try reinstalling Perl:

cd /usr/src
wget http://layer2.cpanel.net/perl588installer.tar.gz
tar -xvzf perl588installer.tar.gz
cd perl588installer
./install

Then run /scripts/upcp –force again to reinstall the cPanel files
