Pyrex / py2exe import interaction

Ok.  I've gone a bit further.  It appears that the problem occurs
during a call to imp.load_module on line 163 of support.py of py2exe
The tail of my trace now looks like...

imputil.py#151 {'__builtins__': <module '__builtin__' (built-in)>, '_extensions_mapping': {'testmod': ('testmod.pyd', ('.pyd', 'rb', 3))}, '__name__': '__main__', '_ModuleType': <type 'module'>, '__doc__': None}.get('__importer__')

AT support.py#160

CALLING imp.load_module(fqname='testmod', fp=<open file 'c:\cygwin\home\cce\prob\dist\test\testmod.pyd', mode 'rb' at 0x007E9390>, pathname='c:\\cygwin\\home\\cce\\prob\\dist\\test\\testmod.pyd', desc=('.pyd', 'rb', 3))

imputil.py#085 IN _import_hook(fqname='string',globals=<module 'testmod' (built-in)>,locals=None,fromlist=[])

imputil.py#088 _determine_import_context(globals=<module 'testmod' (built-in)>)

imputil.py#151 <module 'testmod' (built-in)>.get('__importer__')
Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "imputil.pyc", line 103, in _import_hook
  File "<string>", line 52, in _import_top_module
  File "imputil.pyc", line 216, in import_top
  File "imputil.pyc", line 267, in _import_one

  File "imputil.pyc", line 89, in _import_hook
  File "imputil.pyc", line 152, in _determine_import_context
AttributeError: 'module' object has no attribute 'get'

...

Now, I just tried imp.load_module directly, and it worked.  So,
somehow one of those other "hooks" is firing and doing something
strange...  I don't know where to put trace code to peek

ActivePython 2.2.1 Build 222 (ActiveState Corp.) based on
Python 2.2.1 (#34, Apr 15 2002, 09:51:39) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import imp
>>> name = "c:\\cygwin\\home\\cce\\prob\\dist\\test\\testmod.pyd"
>>> file = open(fn,'rb')
>>> imp.load_module('testmod',file,name,('.pyd','rb',3))
<module 'testmod' from 'c:\cygwin\home\cce\prob\dist\test\testmod.pyd'>
>>> ^Z

So.  I just don't know where else to look at this point.  
Here's hoping!
