JFYI ... I found it.

The main problem was that it was trying to link the C++ libraries here 
at the end and it was finding libstdc++. In this port I am using 
gfortran with clang. I did as in the windows case, I just removed the 
C++ stuff and now I got it to build.

I still have to do some testing before I finish the port.

While here, I think it should be possible to drop libstdc++ into an 
independent port and have all the  g++ ports use libc++ by default.

Pedro.
