I had to change a bunch of directory names to lower case when packaging for some reason I still don’t understand - I noticed that the, now deleted/renamed directories, are still in svn, so something must of gone wrong there. Doesn’t affect me under Linux where pathnames are case sensitive of course, but for everyone else that is a problem. I’ll have a look, though not entirely sure what my options are for fixing this!
As for looking at the source inside the packages its all compiled to pyc files, so you’ve got to go look at the repository I’m afraid, though you can have a look inside the repository using the multify tool, which can decompress a p3d file.
