Very nice project. I was able to compile it on MacOS X 10.6.8 with no changes and just a couple of changes to my directory structure and copying one library (crt1.10.6.o). Apparently Xcode puts everything over in /Developer/SDKs/MacOSX10.5.sdk/usr/lib/* and the compiler wanted it in the actual /usr/lib/. Pretty cool, thanks for publishing your work.
no trouble to install and run, works nicely.
