Thanks Justin.

I unpacked compiler-rt-3.3.src.tar.gz into projects and re-ran
configure/make, but that library is still missing:

$ find /usr/local/ -iname libclang_rt.asan_osx_dynamic.dylib
$

Does the makefile do the right thing? Or do I need to take more
special steps (does compiler-rt-3.3.src need to be renamed)?
