[MapProxy] Difficulty setting up Custom Projections

[Marc Harter]

I have this setup in my proxy.yaml file:

srs:
    proj_data_dir: "/var/www/mapproxy/srs"

In that directory I have a file called 'espg' that contains this:

<103930> +proj=tmerc +lat_0=44.66111111111111 +lon_0=-92.63333333333334 +k=1 +x_0=141732.2834645669 +y_0=0 +a=6378413.671 +b=6357028.9851403 +to_meter=0.3048006096012192 +no_defs <>

When I try to start my development server I get this stacktrace:

$ paster serve etc/develop.ini --reload

Anything I'm doing wrong?  Any help would be greatly appreciated!
