Proj 4 error: no system list, errno: 2

[Ryan Ollerenshaw]

*I just installed MapServer on a new machine and i an not sure why i am 
getting the following error:

Warning*: [MapServer Error]: msProcessProjection(): no system list, 
errno: 2 in */var/www/html/mapserver/display.phtml* on line *13

I know that the epsg file is present because i can locate it with:

$ locate epsg
....
/usr/local/share/proj/epsg
....

Also the following works:

$ proj -v +init=epsg:4326
Rel. 4.4.9, 29 Oct 2004
