Hi Shad,

This means that GEOS was not installed before you built PostGIS from 
source, and so the extra code required was not built into the PostGIS 
module.

To enable this functionality, you need to rebuild the same version of 
PostGIS from source, but ensuring that both GEOS and the GEOS 
development libraries have also been installed first. Then when you do a 
standard "configure; make install", the extra routines should be enabled.


HTH,

Mark.
