 Executive summary: nice try, but this was never a fix, since the relevant
 upstream change was reverted almost immediately.

 All revision numbers below refer to the upstream repository.

 The change in r151044 was reverted (apparently without recognizing that it
 was a regression) in r153182 (by the same person who made the change in
 r151044 :-/ ).  Doing
 {{{
 sudo port clean clang-3.1
 sudo port patch clang-3.1
 pushd dports/lang/clang-3.1/work/trunk/compiler-rt/lib/asan
 svn diff -r 153182:153641 asan_mac.cc | sudo patch -p0
 popd
 sudo port -u upgrade clang-3.1
 }}}
 gave me a successful build but I don't have complete confidence that this
 is a correct compiler.  (FWIW, there's only one patch to asan_mac.cc
 between r153182 and r153754, and this procedure applies that patch.)

 I suppose that
 {{{
 sudo port patch clang-3.1
 pushd dports/lang/clang-3.1/work/trunk/compiler-rt/lib/asan
 svn diff -r 153179:153182 | sudo patch -R -p0
 popd
 sudo port -u upgrade clang-3.1
 }}}
 would have had the same effect but I didn't test it.
