It is not easy to install a perl module just anywhere. The perl module
is a part of a distro package and although the name of the module is
the same, the name of the package in Fedora differs from the name of
the package in Debian etc. In addition, TeX Live is assumed to be
installed as a normal (non-root) user but Linux distro packages
(including those with perl modules) must be done by root. Of course,
the modules can be installed in non-system directories but than they
will have to be copied manually (not as packages) and the user must
know how to set the PERL5INC environment variable. CPAN installation
works for simple modules but complex modules as PerlTk installed from
CPAN often do not work. The problem is that CPAN installs the latest
version but the user might have an older Linux distro with older perl
which is not compatible with the latest module on CPAN. Thus
installation of perl modules from Linux distro packages is often a
better idea.
