libgfortran configuration log file

Hi. Working on a Macbook running OS X 10.8.5 (Mountain Lion), with MacPorts. I
want a "universal" installation of GCC (including Fortran) to run in 32-bit and
64-bit modes. This is failing for me (the pre-packaged 64-bit only is OK).
Here's the bug report on trac.macports.org:
