couldn't link to gcc-compiled binaries for this reason, since I was using
the latest gfortran binary on the gnu compiler wiki (which is the 10.5
version). There is a later one that is built specifically for snow leopard
that I found (
http://hpc.sourceforge.net/). These binaries CAN create 64-bit
executables, but there seems to be a compiler bug that doesn't allow amber
to fully compile (though now ambertools works just fine!). When that gets
fixed and subsequently released as a binary for Snow Leopard, the gnu
compilation will probably finally work easily on snow leopard, though the
configure script has to remove the -m32 flag from snow leopard's configure
process or netcdf will not configure correctly (since gfortran now builds
64-bit by default). This can't be done after configure is run since netcdf's
configure script runs before the config.h file is created.
