export CC=gcc
export CXX=g++

There's a bug in cmake where it picks gcc and c++ as the default compilers. On recent Mac releases, these point to different toolchains (Gnu vs Clang). This will be fixed in the next cmake release (cc and c++ will be the defaults).

So far, I've only built Condor using gnu. I should start building with Clang, as that's obviously the future on Mac. That'll induce me to start tackling all of those warnings.
