Hi Thomas,
Thanks for the reply and help with debugging the problem.  See below for 
details.

OK, here's how I changed the support.py file:
info = _extensions_mapping.get(fqname)
print "*******************************************************"
print "DEBUG-> parent, modname, fqname, get_code, _pyc_suffix:", parent, 
modname, fqname, get_code, _pyc_suffix
print "DEBUG-> info:", info
if info:
     pathname, desc = info
     print "DEBUG-> pathname, desc:", pathname, desc
     # prepend exe_dir to filename
     pathname = "%s\\%s" % (sys.prefix, pathname)
     print "DEBUG-> sys.prefix\pathname:", pathname
     # Should catch IOError and convert into ImportError ??
     print "DEBUG-> desc[1]:", desc[1]
     print "DEBUG-> *** ABOUT TO OPEN FILE..."
     fp = open(pathname, desc[1])
     print "DEBUG-> *** FILE OPENED, fp:", fp
     dict['__file__'] = pathname
     imp_loadmodule = imp.load_module(fqname, fp, pathname, desc)
     print "DEBUG-> imp_loadmodule:", imp_loadmodule
     print "DEBUG-> dict:", dict
     return 0, imp_loadmodule, dict


And here's the output and traceback.  I looked for 
"_extensions_mapping," as it appears to be when the _pyc_suffix info is 
lost, but couldn't find it in my Python22 dir.
