Problem under FreeBSD 2.2.6

I don't know if this is a port bug or what.

I had been happily using Postgres95 (yes 95) with the intention of upgrading
to Postgresql 6.something when I got a 'round tuit'. Well my hand was forced
this weekend when the host machine died a horrible death. I got the latest
release (6.3.2) and it compiles just fine under FreeBSD 2.2.6. However, it
won't run nearly as well. The install and initdb seem to work fine and the
postmaster will start. As soon as I try to 'psql template1', the postmaster
crashes with a 'bad system call' dump. When debug level 3, the following
output is received (sorry for the length) and postmaster dies (the lock file
is still in /tmp).

Any ideas??
