Yes, I know -- but particularly after your response, I kinda doubt that
version is the issue.  ;-)

Curioser and curioser, as Alice said.  AFAICT, there isn't any
_namemapper.pyd anywhere on the system.  (There's a _namemapper.so on my
Mac.)  There doesn't seem to be an official pyd for 2.6, should I use
http://feisley.com/python/cheetah/pyd2.2.1/py26/_namemapper.pyd
?

What are the chances that it will work with Cheetah 2.0.1?  (I'm close
to a production release and would really rather not change Cheetah
versions right now.)  Alternatively, how difficult is it likely to be to
upgrade?

Any clue why Cheetah is so fast outside the .EXE without any
_namemapper.pyd around?
