Same here.

Who said anything about PROJ4?

This is due to my changes to the datum handling, when it was moved
from libcoorcnv to libgis:

	Working file: src/libes/gis/datum.c
	----------------------------
	revision 1.1
	date: 2002/04/12 14:09:32;  author: glynn;  state: Exp;
	Move datum table code (and datum.table) from libcoorcnv to libgis
	Tidy datum table code

I've committed a fix (to both head and release branch).
