This wasn't likely the cause of all your problems.  Try defining
that environment variable again, and check whether "import sys"
really does give a syntax error.  If it does, it's something else,
because all PYTHONPATH should do is let you add more stuff to
the standard search path.  (If you can get import sys to work,
type "sys.path" to see what is defined, and you'll see that the
stuff in PYTHONPATH merely goes at the front, just after the ''
item which means the directory from which the script runs.)

If you are really getting a syntax error, paste the full traceback
into another posting so we can see what it is.  Maybe you were
typing with CAPSLOCK on?  Or you had a module of your own in the
current directory, called sys.py, and it contained a syntax error,
so when you imported it you got confused?  Definitely something 
other than PYTHONPATH, I think.
