This is the approach that I would recommend. Normally my scripts
contain code snippets like this one:
"""
if not hasattr(sys, "frozen"):
from comtypes.client import GetModule
GetModule(r"../../../include/SomeLib.tlb")
GetModule(r"../../../include/SomeOtherLib.tlb")
from comtypes.gen import SomeLibLib
from comtypes.gen import SomeOtherLib
"""
which will generate the code when I start the script with Python,
and which lets py2exe include the generated code into the exe.

Well, it may not be the recommended approach to develop but we (in our company)
do not increment the typelib version numbers on each change we make to our
idl files. OTOH, why do you care about the stat call?
BTW: comtypes in SVN contains an important improvement: Code generated by a
frozen
script will be cached in the filesystem, so if the generated modules are not
inside the frozen exe they will only have to be generated when the application
is run for the first time.
