I have had a lot of success with (using the 2.6.2 sources)

mkdir -p build && cd build && ./configure --with-framework- 
name=Python64 --with-universal-archs=all --enable-framework --enable- 
universalsdk=/ MACOSX_DEPLOYMENT_TARGET=10.5 && make && sudo make  

That builds a 4-way universal binary. --with-universal-archs=64-bit  
will get you just the 64 bit stuff (note that a few of the make  
install steps will fail because of Carbon deprecation but nothing  
important as far as I can see).
