As I mentioned in another reply, this worked for me until I tried to link to
a macports lib (I think some regex lib) that actually used the macports
libiconv (a lot of them don't even if they pull in the dependency).  Then I
was really stuck because I had dependencies on two different libiconv's, and
neither one would link properly.

As such, I consider this a pretty fragile "solution".
