You have found out that the execution of "site.py" inserts
the invalid entries to "sys.path". I remember that there is
a document (it was somewhere on "python.org", when I last read it, but
this was years ago) which describes what "site.py" does.
In particular, it interprets "*.pth" files it finds via "sys.path"
and extends "sys.path" according to the content of those files.
I find it quite likely, that one of those "*.pth" files might
cause the wrong entry in your "sys.path".

I think this is correct: Python expects the directory corresponding
to "prefix" to have subdirectories "bin", "lib/python<version>" and "include".
