I have tried the following by compiling the 9.1 source with the --enable-thread-safety flag and I've tried the libpq libraries provided in the EnterpriseDB build of 9.1. All of this is on Mac OS X 10.6.8 with XCode 4.0.2.
Hm, is there a libpq dylib in /usr/lib? If so, maybe it's capturing the
reference? "otool -L main" would be informative about which dylib is
actually getting called, I think. If it's not what you expected, the
lack of a -L switch in your link command is probably the reason.
