A technique I find handy for debugging mapserver problems, a bit more 
useful than "Internal server error", is to go into the Unix shell and 
use shp2img. Are you able to get into a shell?

I'd use something similar to one of these:
   shp2img -o test.png -m mapfile.map
   shp2img -o test.png -m mapfile.map -d 999
   shp2img -o test.png -m mapfile.map -l lakes,streets

When that fails, it'll give you more information as to what went wrong. 
For example, it will give hints as to shapefiles being transferred in 
ASCII mode, or the TEMPDIR not being writable.
