[pygame] BUG with fix: PyGame crash on Intel Duo Core (Mac OS X 1.4.X)

["James P. Crutchfield" <chaos@xxxxxxxxxxxxxxx>]

Dear PyGamers,

	I recently installed Python 2.4 and PyGame using fink (the Debian- 
derived package
manager) on Mac OS X (10.4.6 and 10.4.7). It was installed on PowerPC  
Macs (dual G5) and
PowerBook G4 and ran fine.
	It was also installed on a MacBook Pro (duo Core Intel), but crashed  
with "Illegal
Instruction". This note is about a work-around that allows PyGame to  
run on the Mac Intel
platform. It also indicates more or less where the problem lies.
	I hope you find this useful.

	Regards,

		Jim

MacBook Pro (due core Intel, 2.16 GHz) 15"
Mac OS X 10.4.6 and 10.4.7:

Fink installer.
Packages: python24 and pygame-py24.

Problem:
	When python script executes pygame.init() it crashes with "Illegal  
Instruction".
	Traceback reveals that the crash occurs in CoreGraphics, which is  
called by WMEnable()
in /sw/lib/python2.4/site-packages/pygame/macosx.py. For example:

Thread 0 Crashed:
0   com.apple.CoreGraphics 	0x90451dc3 _CGSAppShowHideOp + 82
1   com.apple.CoreGraphics 	0x90451d62 CPSPostShowReq + 175
2   com.apple.HIServices   	0x917e2a48 SetFrontProcessWithOptions + 82
3   com.apple.HIServices   	0x917e29f2 SetFrontProcess + 25
...

	The fix:
	(i) Force PyGrame to run macsox.py and not macosx.pyc by renaming  
latter.
	(ii) In macsox.py comment out the line in function WMEnable()

		    # err = d['SetFrontProcess'](psn)

	Consequence: The PyGame window will not be put on top of all others.  
But at least
it runs again.
