Stupid question... you installed Python right? just checking
I dug around in the src and build code in the linkss-0.7.N.zip near as I can tell they would be enough to give you sense of "did the installer work right"
but.... the installer should "just work" - regardless of OS - as the installer would just "Fail" to work at all if it was a file extraction problem.
yeah. totally out of ideas now.
