OK Fixed it myself (maybe I should have looked deeper ebfore raising
this post.

I used dependency walker to check the dependencies of the pyd file. It
indicated that
libeay.dll had a problem (at least one module has an unresolved improt
due to a missing export function
in an implicity dependent module.

Looked and sure enough it was in /windows/system32, dated 4/3/2008.
There were 5 other instances on the box, from things like
Yahoo widget engine, Landesk and vmware infrastructure server

libeay.dll is part of the ssl library and must mismatch with some
other parts of the application.

In time honored manner, deleted from /windows/system32 (did not bother
unregistering) and the problem is solved.
