Exactly. If I was building for my own personal use, I wouldn't bother
with PPC, or even i386 - i'd just go with x86_64. However, as I am
developing software for wide distribution, I want it to be able to run
on as many machines/OS's as possible.

That said, I did sort of get this to work. What I ended up doing was
building for each architecture separately (but on the same machine),
then using lipo to combine the resulting libraries. When I took all
but one architecture flag out of the configure string I used, it
worked- regardless of which architecture I left in. I haven't had a
chance to test this fully yet, but so far it seems to have worked -
lipo reports all three architectures (I didn't bother with ppc64), and
in the initial compile phase at least Qt is happy (still dealing with
other unrelated compile issues there). Apparently PostgreSQL will
happily build for any one of the platforms under Mac OS X 10.6, but
trying to build for multiple platforms at once gives it heartburn.
Given that, I tend to think there was something wrong with the way I
was trying to do it - something missing/wrong from the CFLAGS or
LDFLAGS or the like.

I'm somewhat curious though. I didn't have any difficulties making
universal builds of MySQL and SQLite by simply passing multiple -arch
flags to CFLAGS and LDFLAGS. It makes me wonder what PostgreSQL is
doing differently that causes problems? Thanks for the feedback and
advice!
