3.3.9.2. Installation
Perl's capabilities can be extended by installing additional modules. These modules come in the following forms:
Official Red Hat RPM
The official module packages can be installed with yum or rpm from the Red Hat Enterprise Linux repositories. They are installed to /usr/share/perl5 and either /usr/lib/perl5 for 32bit architectures or /usr/lib64/perl5 for 64bit architectures.
Modules from CPAN
Use the cpan tool provided by the perl-CPAN package to install modules directly from the CPAN website. They are installed to /usr/local/share/perl5 and either /usr/local/lib/perl5 for 32bit architectures or /usr/local/lib64/perl5 for 64bit architectures.
Third party module package
Third party modules are installed to /usr/share/perl5/vendor_perl and either /usr/lib/perl5/vendor_perl for 32bit architectures or /usr/lib64/perl5/vendor_perl for 64bit architectures.
Custom module package / manually installed module
These should be placed in the same directories as third party modules. That is, /usr/share/perl5/vendor_perl and either /usr/lib/perl5/vendor_perl for 32bit architectures or /usr/lib64/perl5/vendor_perl for 64bit architectures.
Warning
If an official version of a module is already installed, installing its non-official version can create conflicts in the /usr/share/man directory.
