[postgis-users] Installing a fully functional PostGIS 2.0 on Ubuntu Linux GEOS/GDAL issues

[THX1138]

Thanks, for your help on this I would have never figured this out as the
config shows my 3.3.1 GEOS, so I figured it was using the right version when
making. 

The problem is that a dependency of libgdal1-dev (the 1.8 version) is
libgeos-dev which installs and older version of the geos, so if I delete
them, I assume gdal will give me an error when making postgis. 

Perhaps I can uninstall gdal and build gdal from source using the 3.3.1
geos, although I bet this would create another mess.

Can you shed some more light on the editing the makefile option?

Thanks again!

Andrew
