Comment(by howarth@…):

 Interesting....if you add...

  python.add_archflags   no

 to the main part of the Portfile, python changes the compile flags from...

 /usr/bin/gcc-4.2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -arch
 x86_64 -D_PYMOL_MODULE -D_PYMOL_INLINE -D_PYMOL_LIBPNG -D_PYMOL_FREETYPE
 -D_PYMOL_NUMPY -D_PYMOL_OPENGL_SHADERS -DNO_MMLIBS -Iov/src -Ilayer0
 -Ilayer1 -Ilayer2 -Ilayer3 -Ilayer4 -Ilayer5 -I/opt/local/include
 -I/opt/local/include/GL -I/opt/local/include/freetype2
 -Imodules/cealign/src -Imodules/cealign/src/tnt
 -I/opt/local/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6
 -c layer3/Selector.c -o
 build/temp.macosx-10.6-x86_64-2.6/layer3/Selector.o -ffast-math -funroll-
 loops -O3

 to

 /usr/bin/gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -pipe -O2
 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -D_PYMOL_MODULE
 -D_PYMOL_INLINE -D_PYMOL_LIBPNG -D_PYMOL_FREETYPE -D_PYMOL_NUMPY
 -D_PYMOL_OPENGL_SHADERS -DNO_MMLIBS -Iov/src -Ilayer0 -Ilayer1 -Ilayer2
 -Ilayer3 -Ilayer4 -Ilayer5 -I/opt/local/include -I/opt/local/include/GL
 -I/opt/local/include/freetype2 -Imodules/cealign/src
 -Imodules/cealign/src/tnt
 -I/opt/local/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6
 -c layer3/Selector.c -o
 build/temp.macosx-10.6-x86_64-2.6/layer3/Selector.o -ffast-math -funroll-
 loops -O3

 whereas I would have expected it just to cause '-arch x86_64' to be
 dropped.
