asan broken?

Is anyone having linking problems when compiling tot with -fsanitize=address? I'm seeing:

Undefined symbols for architecture x86_64:
  "___asan_init_v2", referenced from:
      _asan.module_ctor in test-OIs56r.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

with a fresh llvm/clang build on OS X and:

clang version 3.3 (trunk 177431)
Target: x86_64-apple-darwin12.2.0
Thread model: posix


I’ve recently bumped the asan API version from v1 to v2.
You need to rebuild compiler-rt.


Awesome, thanks!
