This is a touch off-topic, but I just tried building Postgres and it failed
as follows:

So, I have two questions:  1) what gives with the mktemp() stuff, is that
discussed over on the generic users list?  I got the same error building
GNU make.

2) The undefined symbol stuff looks like a missing library, but I don't
know which one.  Could the configure be picking up the wrong locking
mechanism for this OS?

I'm running -current of Sept 27.  Postgres 6.2.

Signature failed Preliminary Design Review.
Feasibility of a new signature is currently being evaluated.
