On unix systems you can generally install your own perl in user space, and not have to worry about modules being a problem. This is ideal, if you have the disk space on the host.

Alternatively, you can install individual packages in your home dir for use with the site's main perl using this formula: (assumes bash shell)

perl Makefile.PL prefix=$HOME
make
make test
make install

You'll want to look at your Perl docs to read about @INC, also.
