[pygame] Pypack

[Jasper <jasper@xxxxxxxx>]

Carrying over from the previous thread about py2exe, etc.  I've messed 
around with Pypack some more, and now recall what turned me off initially.

1) The script to use is called pypackage.py, but the docs and comments 
refer to it as pypack.  Easy enough to fix, but makes it immediately 
clear this is alpha code.  Hence my reticence to dig far.

2) The .exe it generates doesn't work, yielding this error:
Traceback (most recent call last):
 File "runapp.py", line 33, in ?
 File "Myth/Client/legacy.py", line 6, in ?
   from twisted.internet import reactor
ImportError: cannot import name reactor

Sure enough, when I look under the "extlib" dir tree, reactor.pyc is 
missing.  So Pypack apparently missed a static import from my starting 
script -- the 3rd thing I import.  My confidence is not high after 
seeing this, but I gamely copy over reactor.pyc by hand, and ...

Traceback (most recent call last):
 File "runapp.py", line 33, in ?
 File "Myth/Client/legacy.py", line 8, in ?
   from Realms.Myth.map                       import MythMap, Plains
ImportError: No module named Realms.Myth.map

This is the first import of my code.  Turns out Realms.Myth.map is 
stored under Realms/app/Myth.  This leaves me guessing that I actually 
need to run pypackage from the directory /containing/ my root dir -- in 
contrast with what the docs say.

Ok... so I try this, and momentarily my reservations vanish, as I see my 
opening Menu!  Until I try to play a game, and see some odd error from PIL:
...
 File "C:\Python24\Lib\site-packages\PIL\Image.py", line 1289, in save  
exceptions.KeyError: '.png'

Looking at the PIL source it looks like it's expecting some sort of 
extension to handle .png's, which is apparently missing?  Hmmm, I seem 
to recall a PIL entry for py2exe, so I check that.  I hack my code to 
force import of PngImagePlugin and trick PIL into thinking everything is 
ok, and PIL now works.

But now I find that twisted.python.threadpool.pyc is missing, because 
twisted.internet.base imports it dynamically.  I would guess this is to 
avoid Python's refusal to handle circular imports, which is something 
I'm also forced to do... I copy threadpool.pyc, and then realize that 
everything threadpool imports I'll also have to manually deal with, or 
change my code to force import...

Clearly I need someway to manually include certain things, but the 
Pypack docs give no indication of how to do this...  Is there a way to 
force Pypack to import missing things?  I don't know, and so I'm back to 
futzing with py2exe, for which my .exe is presently looking for 
datafiles in a different place than py2exe put them.  :-(
