[Proj] Projection problems using Mapserver 4.6

[William Hudspeth]

Hello,

I am using Mapserver 4.6 and Proj 4.4.7 on Fedora Core 3. I am using a
map file where map and layer projections are defined as:
 
 PROJECTION
   "init=epsg:4326"
 END
 
 My WMS GetMap requests look like this:
 

http://falstaff.unm.edu/cgi-bin/mapserv?
map=reason/dream_map.map&VERSION=1.1.1&REQUEST=GetMap&BBox=-120.000,26.000,-97.000,44.000&SRS=EPSG:4326&Width=570&Height=446.086956522&Layers=GRASS_SHADED_RELIEF
 
 And, regardless of which map layer I call, I get the following error.
 

 msProcessProjection(): Projection library error. projection not named
 
 I would much appreciate any enlightenment!
 
 Thanks, Bill
