 My guess here is that g++-mp-6 can't find /opt/local/lib/libstdc++.6.dylib
 in `-isysroot /Developer/SDKs/MacOSX10.4u.sdk` Try a quick hack like this,
 to link in /opt/local to the SDK so it can find it. (or figure out how to
 change the -isysroot to "/".
 {{{
 cd /Developer/SDKs/MacOSX10.4u.sdk/
 sudo ln -s /opt/local .
