[mapserver-users] python mapscript AGG problem

[Guillaume Sueur]

Yes, you can, by compiling your own version of MapServer including agg
support and running setup.py install from mapscript/python directory.
But you'll run into agg static lib problem, that you can fix following
the included instructions from PerryGeo (http://www.perrygeo.net/wordpress/)

Best regards,

Guillaume
