__neg__, __add__ work only inside module

[GoogleCodeExporter]

What steps will reproduce the problem?

% shedskin -e Vector4.py
% make
% python
Python 2.5.2 (r252:60911, Jan 20 2010, 23:16:55) 
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from Vector4 import Vector4
>>> a = Vector4(1, 2, 3, 0)
>>> -a
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary -: 'Vector4.Vector4'
>>> a.neg()
<Vector4.Vector4 object at 0xb74ab320>
>>> a - a
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for -: 'Vector4.Vector4' and 
'Vector4.Vector4'
>>> a.sub(a)
<Vector4.Vector4 object at 0xb74ab340>

What is the expected output? What do you see instead?

Operator overrides work fine inside the module.
If you don't use '-e' and build Vector4 as a standalone executable, it works 
fine, and the output is:

% ./Vector4
<Vector4 instance>
<Vector4 instance>

However, if you build it as a module and import it, suddenly the operators 
don't work.  You can work around this by adding in non-operator functions, but 
if you're porting a larger project that does a lot of math [as I was trying to 
do], it's a big pain.

What version of the product are you using? On what operating system?

This is shedskin 0.5 on Ubuntu 9.

thanks for the issues! I will try to have a look at supporting overloading in 
extension modules later this week.
