Hi,

I would suggest:

  o trying to see if "proj -V +init=epsg:102003" works properly.
  o Does you mapserver running under apache have read permissions
    down into /usr/local/share/proj?
  o set the PROJ_DEBUG environment variable and see what it reports
    about opening supporting files.  (just set it to anything).
  o Set the PROJ_LIB environment variable to /usr/local/share/proj

I think the mostly likely problem is not having read permission to
the file for the user under which your mapserver runs.

Good luck,
