Log Message:
Update to 1.5.0.  Some rough edges due to pkgsrc's replacement of
pgsql's Makefile.shlib are patched around.  ('make test' passes on
netbsd-5/i386 with postgresql84.)

This is a major release adding a significant number of new features including:

    * New "geography" type for managing geodetic (lat/lon) data
    * Performance-enhanced distance calculations
    * GML and KML format readers
    * Improved shape loading GUI
    * And more!

Release Notes
Important Changes

    * =~ operator now indicates bounding box equality, not feature equality
    * GEOS 3.1 is now the minimum accepted version of GEOS
    * GEOS 3.2 is needed if you want to use enhanced buffering features and \ 
ST_HausdorffDistance
    * GEOS, LibXML2, and Proj4 are now mandatory dependencies
