Well if you figure out what is needed I can get it into autoconf.

The system used to be a lot more portable, as time went by more people
started working with it and we were under pressure to produce versions
for specific OS's... So the system is a bit less portable today
unfortunately, but our aim is to fix these things as possible so it's
great to see people running it on all kinds of things!

I don't know about 6.5 (we don't have any IRIX boxes here) but Shawn
Pearce sent us this earlier:
