 I do not know anything about Mountain Lion but on Lion there are 3 files
 in /usr/lib with the prefix crt1.
 {{{
 lipo -info /usr/lib/crt1.*
 Architectures in the fat file: /usr/lib/crt1.10.5.o are: x86_64 i386
 Architectures in the fat file: /usr/lib/crt1.10.6.o are: x86_64 i386
 Architectures in the fat file: /usr/lib/crt1.o are: x86_64 i386
 }}}
 I do not understand why the linker is looking at crt1.10.5.o rather than
 crt1.o.
