This one if now fixed upstream but you will probably hit others (I am now fixing one in nettle for instance). So expect to get everything building again in the next days.

As such they don't appear to be backward compatible for use with Xcode 4.6.3. This being the case, I've been trying to build 1.2.0 myself using Xcode 4.6.3. The repo that I'm building from:

I did a lipo –thin on both architectures (i386 and armv7) and then used ar to extract the respective archives. Checking with otool on the libcairo object files, both seem to be correct:
