I managed to use Python 2.7 from python.org 64-bit version. I forced cx_Oracle to build only 64-bit binary and forcing to use correct Mac OS X SDK. distutils picks the wrong Mac OS X SDK, i.e. MacOSX10.6.sdk instead of MacOSX10.7.sdk. If you would check the output (OUTPUT), you can see that for the second command it's referring to both 10.6 and 10.7 SDK. Is there any problems how disutils picks Mac OS X SDK? I also import the library, but I am getting warning (WARNING). Any advices are very much welcomed.

Looks like 10.6 SDK is picked because Python was compiled using that SDK.
