Comment (by kencu):

 That might work - your skills in that area are beyond mine.

 But I suspect in the end this will most likely be resolved by turning off
 the libfuzzer build on SnowLeopard. Usually stuff like that is done with a
 cmake variable without too much trouble, and there are other examples in
 the llvm/clang Portfile of similar.
