[MapProxy] Difficulty setting up Custom Projections

[Marc Harter]

Tried Ubuntu 10.04 and am ending up with the same errorno: 2.  The file is named lowercase "espg" (without quotes) and no extension right?  That's the only file I have in the srs directory.

Thanks for your time,
Marc

That looks good and it works on my system.

"no system list" means that the projection init file was not found.
Can you double check that you have a /var/www/mapproxy/srs/epsg file
that is readable by the user.

If a specific EPSG code is not found, the error should be "no options
found in 'init' file".

I have to admit that the error messages from pyproj are not very
helpful.

Oliver
