Benjamin,

I haven't traced through everything you have tried, but permissions can
certainly be an issue under some circumstances.  Note that PROJ only has
the permission available to the cgi-bin process it is called from when used
in a web environment.  So if your webserver runs cgi-bin programs as "nobody"
please verify that the nobody user has read permissions on
/usr/local/share/proj/epsg.

You should also verify that things work fine in your commandline environment.
For instances, does shp2img work on your map?  Does proj?  Try this:

warmerda at gdal2200[90]% setenv PROJ_DEBUG
warmerda at gdal2200[91]% proj -v +init=epsg:27700
pj_open_lib(epsg): call fopen(/usr/local/share/proj/epsg) - succeeded
#Transverse Mercator
#       Cyl, Sph&Ell
# +init=epsg:27700 +proj=tmerc +lat_0=49 +lon_0=-2 +k=0.999601 +x_0=400000
# +y_0=-100000 +ellps=airy +units=m +no_defs

Best regards,
