Psql and OS X

I'm seeing lots of funny things happen with psql and MacOS X. I had the
readline libs installed before I compiled PG (which compiled clean as a
whistle BTW) -- but still I have no command buffer and about half the time
selects, / commands and such will return crazy formatted results (well, the
results are not formatted I should say).. I'm using BASH as the shell and
the terminal program that comes standard with OS X... I notice that there is
no .psql_history file being written..

I reinstalled a binary distribution that claimed to have compiled support
for readline in, but I'm not positive.. Still, the same thing happened when
I compiled 7.2.1 on this box myself...

Is there a way to see now if psql found the readline libs?

Any other ideas? 

Thanks!!
