import pyd from zip file

[John Keeling]

I'm using Py 2.3.4, and have been trying to import a pyd that has been
compressed in a zip file. It is not found with an ImportError. The pyd
works fine when uncompressed. I've had no problem importing py and pyc
files from a zip file.

Am I doing something wrong? Is zipimport not designed for pyds? ... or
is it an ommission in the functionality of zipimport? I looked at the
bugs database, and didn't see a mention of this.
Thanks,
John
