Postgresql on m68k

[weich3_(_at_)_earthlink_(_dot_)_net]

Hi there, I'm trying to make the Postgresql port on an m68k system. I've
got OpenBSD 2.4 installed. Whenever I try to make the port it errors out on
part of the backend. An example error:

storage/SUBSYS.o: Undefined symbol `_S_INIT_LOCK' referenced from text segment

That's the first message that comes up. There are several others that
follow before the make kicks out. Each prints a line about undefined symbol.

Has anyone run into this before? If so, any suggestions on what to do to
get it to work? I hope this is enough information. If not, ask and I'll
supply more if I can.
Thanks in advance.
