clang, not llvm-gcc, is the default compiler for Xcode 4.2 and later.

Do you build manually with llvm-gcc-4.2 as well? I can verify the failure with `port install flow-tools` (which uses clang), but `sudo port install flow-tools configure.compiler=llvm-gcc-4.2` works. So the issue is triggered when building with clang.

There is no maintainer for this port but it would be helpful if you could open a ticket (http://trac.macports.org/) and attach the log, you can also add my workaround above so it's documented for other users that hit this.
