i would probably read up on installing perl into your home directory. even if you want to use the alternative version with other users, it's probably the same general setup. you might have to change path variables before you run (or maybe just 'use lib'). however, i recall seeing in the documentation installing cpan modules for a locally installed perl and all. though, if you're doing this as part of a test bed, you might want to look at a solution that allows for snapshots (chroot on a lvm disk, vmware, possibly kvm, etc) > > -- > Regards, > Alex > > -- > To unsubscribe, e-mail: beginners-unsubscr...@perl.org > For additional commands, e-mail: beginners-h...@perl.org > http://learn.perl.org/ > > >
