the only thing that comes to mind is looking around in /proc/self for
something useful.  I believe the standard solution to this problem is
that you  use a #define for the path of the data in the source, and then
use the build system to arrange for that define to be defined as
whatever the path should actually be.  So what whould generally happen
is that autotools stuff would arrange for DATA_PATH to be defined as
what ever the make variable DATADIR is.  This should be fairly portable,
but I don't have an OSX box so....
