When I run

(or any postgis function for that matter)


Hi Regina,

Looks like PostGIS needs to be linked against the Geos library.

When you run configure use the "--with-geos=" directive, and point it to the full path of where "geos-config" is located. For example, if geos is installed to /usr/local, the configure option might look something like this:

        --with-geos=/usr/local/bin/geos-config

Hope this helps.
