If you just want to clone your home installation, copy the perl/html, perl/lib and perl/site/lib directories on your usb stick and from there over the fresh installation.
I'm not really sure what the level of expertise/confidence with perl of the OP is, but to be safe it may be worth to remind him that if the modules to install comprise binary ones, then the two versions of Perl must be the same. Who knows? Maybe he has 5.6.1 at home and has installed 5.8.7 at his friend's...
