Richard,

OGR uses the default search rules to find proj.dll unless you define the
PROJSO environment variable.  If that is defined, then it is name of the
PROJ DLL to load (include an absolute path to find it anywhere).

I think if PROJ.DLL is in your PATH that should normally be sufficient.

Note, FWTools links directly against PROJ.DLL so uses normal startup rules
to find the DLL while the default GDAL build loads the DLL dynamically the
first time it is needed.

Best regards,
