You will need to attach to the python program while it is running with the LLDB
Xcode project. To do this, just run your python script and make sure it is
using the debug version of the LLDB.framework that you have built. Then in
Xcode attach to the python process. With Xcode 4, just use the Product->Attach
to Process->Python. Then set a breakpoint in SBTarget.cpp in the LaunchSimple
command and you can step through and see what is wrong. You can repeat with a
fresh copy of the LLDB sources that use Python 2.7 and see what changed.
You might also check the SWIG files and the scripts that generate the SWIG
C/C++ to Python binding and make sure they aren't outputting files that
targetting python 2.7.
