This probably won't help you, but there has been noise on two other mailing lists I monitor (CMake being one) that suggest people are having similar problems. It seems that Snow Leopard (and the new GCC compiler bundled with it) defaults to 64 bit treatment or something.
That is exactly true. If you want to force 32-bit executables, you can give the -m32 flag (similarly, there is a -m64 flag for 64-bit).
However, you can't just special-case snow leopard, because there is a number of 32-bit intel macs, on which you can install snow leopard, which themselves will default to 32-bit executables!
The only (sane) method I've found to solve this is to do one of two things.
1) Just use the system setting. 2) Explicitly specify -m32 and -m64 on all systems.
Just to clarify, what is the reason of the original error, quoted below?
