I assume this thread was discussing the following:

https://sourceforge.net/tracker/index.php?func=detail&aid=544084&group_id=5988&atid=105988

As far as I can see, the patch is not yet there (or did I misplace it 
somehow, sorry if so), did you (Evan) find it anywhere?  If there is 
someone in the know (Bob?), I would like to see the patch.  In 
particular, I'm interested in whether this is something we can adopt 
immediately for the 2.0.1.05 release, or whether it has significant side 
effects.

The renaming of the __init___.so/pyd files is something I'm planning for 
all platforms, which should make py2exe somewhat happier as well.  I 
would be quite happy to have this in 2.0.1.05.

I have no background information on the:

	OS X requires ranlib for static libraries

problem, I am assuming the solution is merely to add the library to the 
list of libraries in setup.py for the "interface_util" static library 
(if the os is OSX).

Similarly, no background on the:

	OS X GLUT changes the working directory on glutInit

problem.  I am assuming this is where the "working around" comes in.  
This sounds more like a GLUT error that should be reported to either the 
GLUT people or Apple, but if we can work around it without causing too 
much ugliness (and without breaking if the underlying error is fixed), 
I'm willing.

BTW: These really seem like three separate patches, one for each of the 
three problems.  We're still quite informal about these things, but it 
would be nice to be able to review each issue individually, rather than 
needing to pull apart a patch file's effects to see what's being changed 
and how.  I'd rather have a combined patch than no patch, of course :) .

The changes in Jack's original patch are already integrated into the 
2.0.1 release, even the """self.output_dir = "" # Try by Jack""" voodoo, 
though I still have no idea what this was for.  If someone can produce a 
patch for building on OS X, I'd love to review it and integrate it.  If 
you can't get the SourceForge file upload to work, and the patch is less 
than 10 MB, you can send it directly to me.

Despite there being "1-click" installation, I would still like PyOpenGL 
to build out of box with the standard "setup.py install" for OS X 
(though I understand that changing the described makefile is out of 
scope, we can include that in the build instructions).

Enjoy yourselves,
Mike
