Attached is the full main.log and the config.log files.

Apparently, "-arch" flag is passed to gcc-mp-4.5:
configure:3818: /opt/local/bin/gcc-mp-4.5 -pipe -O2 -fno-common -arch x86_64 -arch i386 -I/opt/local/include -DNDEBUG -DpgiFortran -L/opt/local/lib -arch x86_64 -arch i386 conftest.c  >&5
cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-arch"
configure:3822: $? = 1
configure:3860: result: no

I've been searching the documentation to learn what "muniversal portgroup" was, without much success so far.
Can you point me to the right place ?
Does this imply some rewritting of the portfile ?
Or can it be passed as command-line options ?

Thank you for your help,

Julien
