Sam,

I trust you did a make clean before the make install, right?  When
compiling PROJ.4 (specifically src/pj_open_lib.c) was there a
"-DPROJ_LIB=..." on the compile command line?  Did it point to the
directory where the epsg translation file got installed?

Note you don't have to recompile MapServer when fiddling with the
PROJ.4 installation.

I would suggest verifying the finding of the EPSG translation file with
the PROJ.4 commandline program.

eg.
warmerda at gdal2200[137]% cs2cs +init=epsg:4121 +to +init=epsg:4326
0 0
0d0'2.419"E     0d0'8.03"N -199.865

I would add that errno=13 is apparently EACCESS indicating a permissions
problem, not that the file doesn't exist.  Perhaps whatever user your
mapserver/apache runs as (nobody?) does not have read/execute permissions
down to the directory and files in question?

Best regards,
