GEOS

QGIS uses GEOS to properly fetch features from the database when doing an identify or select. You can still view PostGIS layers without GEOS, but you will not be able to create a selection or identify a feature.

If you choose to proceed without GEOS support, QGIS will warn you each time you load a layer from the database.

To install GEOS:

Download GEOS source from http://geos.refractions.net
Untar GEOS
```
  tar -xzf geos-1.0.0.tar.gz
```
Change to the GEOS source dir
```
  cd geos-1.0-.0
```
Follow the instructions in the GEOS README file to complete the installation. Typically the install goes like this:
```
  ./configure
  make
  make install
```
