Another way that will work with some providers is to set an environmentvariable PERL5LIB to the path where you want to install the Modules (somewhere in your home) and then install them there.
A better way might be if it was possible to put it into a directory of your home, find the path of the current running script with use FindBin qw($Bin); and then load the Module with use lib "../../myModules"; and require MyModule and, if needed, import. Sometimes it might help if you do so in a BEGIN-Block...

But I consider talking with the provider a better way ;-)

Best regards,
perl -e "print a|r,p|d=>b|p=>chr 3**2 .7=>t and t"
