No, just one link to libpq.5.dylib. There's nothing else in there
you'd should need to link with, except for very tightly integrated
packages such as Slony, which you'd probably want to install in the
PostgreSQL tree anyway (if not, your probably the sort of person who
would be building the server from source as well anyway).

Yeah, I use Macports as well. For the most part, it doesn't integrate
with OS X - that's why it's all kept under /opt.

Yup.

That's very old. I'd stick with the installer or MacPorts.

Oh, they won't. You won't find many apps in MacPorts that do I'd wager
- just a few GUI ones which don't use X11 (such as pgAdmin).
