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.
