In addition to the library files and executables for PROJ4,
one also needs to have the datum files which have the
definitions of the various coordinate systems for proj.exe
and the library routines to use.  If you don't have them
installed, then you will not be able to convert coordinate
projections.  You'll either need to set an environment
variable or get an additional package with those files.
I don't know what or where that would be for the Mac.
