Are you forcing -arch i386 ? It may be you are hitting the problem with APR and universal binaries under OS X. With Snow Leopard, this no longer works correctly, and trying to compile both as i386 and x86-64 results in problems because the actual C header files are different depending on which version is built. A patch was put in awhile ago to fix this, but was vetoed.
