This should not be the case.  Which version of CMake are you using?

Also, you _must_ set CMAKE_OSX_SYSROOT to the 10.4u SDK.  Without using
the SDK, you are not guaranteed to be able to link properly.

You should not have to do that.  BTW, are you familiar with the 'lipo'
command?  See 'man lipo'.  You can use it to confirm if an executable is
ppc/i386/ppc64/x86_64.
