mac os 10.2 and postgresql

I noticed that the most recent code in the Postgres CVS will compile
on Mac OS 10.2, but I've had problems with it. I keep receiving i/o
errors, which I didn't receive with Mac OS 10.1.5 and Postgres 7.2.
Anyways, is there any way to get Postgres 7.2 working on Mac OS 10.2?
I'm guessing that as a lot of people upgrade to OS 10.2 others will be
asking this same question.

Thanks.
