One of the reasons I was accepted into GSOC was because I was able to successfully build and run PySoy on Mac OS X. On a whim, I decided to jump into OS X and run tests on some of the newer iterations of libsoy (e.g. Simple.gs).
Nothing doing. Libsoy and pysoy still build, but there is a nasty memory leak. The test crashes with a bus error (EXC_BAD_ACCESS). This happens with hboxTest and vboxTest as well. I am thinking there is some quirk in Apple's OpenGL implementation that is causing this. I have to focus on development, so I'll continue working on ubuntu. But I really want to look into this.
