I'm glad I'm not the only Dreamcast coder around these parts that uses Mac OS X.
Anyway, If you have the Developer Tools installed on Mac OS X, its fairly easy to get a toolchain set up for compiling Dreamcast stuff. I used a Makefile called dc-chain to build mine, but it does require a few little changes to the basic sources of GCC, if I recall correctly (deleting .m files from the sources, I think).
Just for reference, I'm using the following versions for my DC tools:
GCC - 3.4.6
Binutils 2.17
Newlib 1.10.0 (I think, I'm not entirely sure though, its been quite a while since I built the tools I'm using now).
