Aaron,

This generally means that MapServer can't find your epsg coordinate
system file.  Try setting the PROJ_LIB environment variable to point
to the directory holding the "epsg" file.

You need to provide an explicit definiation of the ellipsoid for a valid
latlong coordinate system.  Add "ellps=WGS84" for instance giving you:

  PROJECTION
   "proj=latlong"
   "ellps=WGS84"
  END

Good luck,
