Hi bigmacbear, this is totally over my head (I don't have to use any Sun boxen where I work), but I've had the odd interesting problem with HP-UX systems, though not quite as involved. I think you should also post your advice to whatever related forums and newsgroups you can find (unless you have already done so). I know if I had a problem installing something, even if it was perl related, on an HP-UX box I'd probably search google groups and/or the HP website first.
