Has anybody run TileCache under mod_wsgi?  Any pointers on how to set it
up?  I'm doing something wrong, and the documentation on this is pretty
sparse.  Here's the error I get in my apache logs:

mod_wsgi (pid=21465): Target WSGI script
'/usr/local/apache2.2/htdocs/tcwsgi/tilecache.wsgi' cannot be loaded as
Python module.
Traceback (most recent call last):
File "/usr/local/apache2.2/htdocs/tcwsgi/tilecache.wsgi", line 2, in
<module>
from TileCache.Service import wsgiApp
ImportError: No module named TileCache.Service

Do I have to move TileCache into "/usr/local/lib/python2.6/"  (my python
library directory) ?

tilecache.wsgi is merely a copy of tilecache.fcgi.
