Interesting. This is the line causing the problem:

# Append ./build/lib.<platform> in case we're running in the build dir
# (especially for Guido :-)
if os.name == "posix" and os.path.basename(sys.path[-1]) == "Modules":
     ...

Looks as if sys.path is empty at the time site.py is loaded.

I tried a similar setup (no PYTHONPATH set, no PYTHONHOME) on
Linux:

private/tmp> ./cgipython test
'import site' failed; use -v for traceback
Hello World!
['.']

with test:

import sys
print 'Hello World!'
print sys.path

The problem goes away if you define the environment variable
PYTHONPATH as empty.

I'd say this is a bug in site.py; I can't see how it can assume
that sys.path is always set. I've fixed this in Python CVS.
