Anyone know what I'm doing wrong?
EDIT: I've solved it - at least, for the first two sections. On Mountain Lion, the location of the SDK is different. Just replace '/Developer/SDKs/MacOSX10.6.sdk' with 'Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk' in every instance, and it should work!

ANOTHER EDIT: Now I'm having problems with Imaging-1.1.7. Looks like gcc-4.0 isn't there either. Time to go rooting.
