I'd have a look at line 169 of DynaLoader.pm, and compare whatever incantation is there with the manpage for shl_load. I'd have a look myself but having neither HPUX nor Perl 5.00503 handy, I can't help you directly, I'm afraid.

So this answer may well be vacuous drivel :). Hopefully it will point you in the right direction though.
