Comment (by jeremyhu@…):

 Ah, sorry I missed that.

 The subports intentionally don't install a /opt/local/lib/libstdc++.dylib
 symlink because that would cause clang++ to link against
 /opt/local/lib/libstdc++ instead of /usr/lib/libstdc++ and thus possibly
 infect clang++-generated code with the same issues plaguing g++ (libc++abi
 vs libsupc++ in the same process).
