[DebianGIS] Updating GEOS package to 2.2.3?

[Sean Gillies <sgillies@frii.com>]

How much effort would be involved in updating the GEOS package? I'd like 
to help as much as I can. 2.2.3 has some crucial fixed and improvements 
that benefit people using GEOS in applications other than PostGIS.

Cheers,
Sean
