Publisher/Vendor/Repository and License Type
https://www.perl.org, Open source
Each cluster has a version of Perl that is part of the Operating System (OS). Some perl scripts (usually such files have a .pl extension) may require particular Perl Modules (PMs) (usually such files have a .pm extension). In some cases particular PMs are not part of the OS; in those cases, users should install those PMs; for background and a general recipe see HOWTO: Install your own Perl modules. In other cases a PM may be part of the OS but in an unknown location; in that case an error like this is emitted:
Can't locate Shell.pm in @INC; and users can rectify this by locating the PM with the command
locate Shell.pm and then adding that path to the environment variable
PERL5LIB, e.g. in csh syntax:
setenv PERL5LIB "/usr/share/perl5/CPAN:$PERL5LIB"
Usage on Owens
To configure your enviorment for use of a non system version of Perl, use command
module load perl. This will load the default version.
Installing Perl Modules
To install your own Perl modules locally, use CPAN Minus. Instructions for installing modules for system Perl are available here. Note that you do not need to load the cpanminus module if you are using a non-system Perl.
