I meant to mention this earlier, but for those of you who are running into various issues using the binary distribution on 10.3 (which was actually built for 10.2-gcc3.3), you can try Rob Braun's unofficial 10.3 binary distribution.
Note the use of the word unofficial. It's not officially supported by the Fink folks and may be incomplete or out-of-date. That said, he's pretty good about keeping it reasonably updated.
