deffinately got a thought.. it's called CPAN - a cli utility that let's you log into it- and install remove, whathaveyou- modules etc.

it's like having a fluffer- or your own automechanic if you're a race car driver.

i know, it doesn't address your error specifically. But.. maybe the install is doign something funny? maybe using cpan will let you install, if not.. then yours is perhaps not a perl problem?

put some energy into getting cpan to work on the shell- who knows.. it might already be on your box! do a locate cpan or just try cpan on your box, then do install themoduleyouwant and hit enter.
