HPUX is problematic in my experience. Anything you want to do that has a standard approach on other *nix systems, has to be dealt with differently on HPUX. I don't know why you are seeing the problem you describe, but a quick google search using these parameters "installing perl modules on HPUX" pointed to some spots you may want to check out.

• CPAN Ports

Based on the version of Perl that is being reported in the warning you posted, I am guessing that you are running an older version of HPUX. You might also want to talk to the sys admin (assuming it is not you) and see if there is a binary install available from one of the depots out there... . I know it is not much, but hope this little bit helps.

Good luck :-)
