If you have shell access to that machine, you can download the nedded modules, unpack them and then follow the usual procedure with a simple variation:

• perl Makefile.PL PREFIX=/path/where/you/can/write
• make && make test && make install

Don't forget that some modules rely on others in order to work properly, so you'll have to do the same over and over again, potentially.

Also, some modules require C libraries or non-Perl modules to be present (e.g. openSSL), you can install those following the instructions, usually during the configuration phase you type something like

./configure --prefix=/path/where/you/can/write

then follow the instructions for the Perl module and find out how to specify the path for the required library.

Finally, as it has already been posted, remeber to update your @INC

This document can be useful, especially section 7 which deals with CPAN as well.

And be careful not to run out of your quota :-)
