Hm that might be true.
I updated to the latest 1927 build but i can still reproduce the  
problem even with this stupid simple example:

#--------------------------
import time

import pygame
from pygame.locals import *

pygame.init()

SCREEN = Rect(0, 0, 450, 450)
screen = pygame.display.set_mode(SCREEN.size)

time.sleep(5)
#--------------------------

This still produces the same error (base.so) when run through py2app.


# Fast forward 4 hours since writing the above


I have now stepped through the whole py2app and pygame init code  
(inside the generated app) and I now believe that this is a problem  
with either py2app or my system.

Py2app generates a "loader" module for each c extension. This loader  
basicly loops through sys.path until it finds one that ends in "lib- 
dynload". For reasons unclear to me the lib-dynload in the sys.path  
used is the one in my system python rather than in the lib/python2.5  
dir inside the app bundle.


However by placing

sys.path.insert(0, os.path.join(base, 'lib', 'python2.5', 'lib- 
dynload'))

inside the py2app __boot__.py file (base is provided py py2app) I  
finally got both my sample and the original "problem" working.


So I'm sorry to have "barked up the wrong tree". If I find a more  
elegant solution to the problem i will post it here.

Bye
Ulrich
