[mapserver-users] mapserver files to subdomain results in '500Internal Server Error' when mapserv executable accessed through url

[Steve Lime]

Typically I would think this is a linking error. That is, the mapserv binary can't find the shared
libs it needs to run. You probably need to configure apache further. There's a LD_LIBRARY_PATH
env variable that you can look into setting.
