Yeah, I hit the same problem recently with Mavericks / Xcode 5.0.2. I noticed that the Mac OS X 10.8 SDK in the Xcode.app bundle has the Python framework - the 10.9 SDK does not. If I change the Base SDK setting to "OS X 10.8", lldb builds. The diff for your project file after doing this will look something like

I don't know if the Mac OS X 10.8 SDK is available by default when you install Xcode 5.0.2. It might have been one of the optional downloads I installed via Xcode Preferences > Downloads.

I believe the problem is there is a Python.framework in the SDK, but it is empty (no headers). If you remote the empty Python.framework from the SDK, it should fall back to the installed version.

The build instructions seem to suggest that this should be straightforward, but after selecting the "lldb-tool" scheme and starting the build as described, after a while I get a build failure with "'Python/Python.h' file not found', referring to the source file lldb-python.h.
