Comment:

 Hmm, ok. Well that log at least confirms:
 {{{
 configure:2724: checking how to run the C preprocessor
 configure:2759: /Developer/usr/bin/clang -arch i386 -arch x86_64 -E
 conftest.c
 clang: error: cannot use 'cpp-output' output with multiple -arch options
 }}}
 I'm wondering why this port is sending `-arch` flags to cpp; MacPorts
 doesn't usually do that since the C preprocessor has no use for `-arch`
 flags.

 It looks like this is fallout from r89472, which was to fix #28376.
