My mistake. Jumped to conclusions there.

Your experience is why I don't use installers anymore, though... I
used to build postgres from macports, then from source, but these
days I use homebrew... if you haven't heard of it, you should
check it out... it's sort of the sane macports, works with what
you've already got so the dependency situation is much, much nicer.

Yeah. Homebrew :D

Homebrew :D

Macports sucks in this particular way.:(

I'm really glad that worked!
