I compiled PROJ.4 with the standard instructions, nothing fancy at
all. It has worked fine with MapServer, PostGIS, GDAL and GEOS
installations so far. GRASS is the only one choking up with the "file
is not of required architecture" message, so I am loath to tinker with
what works with 4 other programs just so it can possibly work with one
other program, and possibly break the other four.

could it be because I first did the following

export CFLAGS="-arch x86_64 -Os"
export CXXFLAGS="-arch x86_64 -Os"

I will try again without those flags and report back.
