 |sys.path *is* already global, though only accessible via the
 |sys module's namespace. Just give it a try.

I'd already tried that.  It's effect doesn't appear to be global:

   # Augment search path to pull in our C library wrappers
   sys.path.insert( 0, '/home/mylogin/Wrappers' )

   import MapFile

This allows Python to find MapFile, but this doesn't allow MapFile to
import other modules in that same Wrappers directory.
