[Q] Newbie: PIL install for NT works fine but Win98 not...

[Reader]

I am trying to quickly get up to speed on Python for OpenGL programming.
One of main obstacles is:

>>> im = Image.open("C:\development\python\NeHe Ports\crate.bmp")
>>> im.tostring("raw", "RGBX", 0, -1)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "C:\Program Files\Python\PIL\Image.py", line 325, in tostring
    self.load()
  File "C:\Program Files\Python\PIL\ImageFile.py", line 125, in load
    self.load_prepare()
  File "C:\Program Files\Python\PIL\ImageFile.py", line 175, in load_prepare
    self.im = Image.core.new(self.mode, self.size)
  File "C:\Program Files\Python\PIL\Image.py", line 40, in __getattr__
    raise ImportError, "The _imaging C module is not installed"
ImportError: The _imaging C module is not installed

The exact same file pil-win32-991101.zip seems to work fine on NT, at least
I can get the tostring call to work.  However, my 98 box is not working.

I have tested my python path:

>>> print sys.path
['', 'C:\\Program Files\\Python', 'C:\\Program
Files\\Python\\Lib\\plat-win', 'C:\\Program Files\\Python\\Lib',
'C:\\Program Files\\Python\\DLLs', 'C:\\Program
Files\\Python\\Lib\\lib-tk', 'C:\\PROGRAM FILES\\PYTHON\\DLLs', 'C:\\PROGRAM
FILES\\PYTHON\\lib', 'C:\\PROGRAM FILES\\PYTHON\\lib\\plat-win',
'C:\\PROGRAM FILES\\PYTHON\\lib\\lib-tk', 'C:\\PROGRAM FILES\\PYTHON',
'C:\\PROGRAM FILES\\PYTHON\\Numeric', 'C:\\PROGRAM FILES\\PYTHON\\PIL']

Which includes PIL, and lib-tk which I think are the main places for the
Image tools.

I installed python using: py152.exe and the PIL library seems to be for the
same version.  I also installed PyOpenGL.

Any ideas on how to address this?

Thanks,
