[postgis-users] Problems installing PostGIS on Red Hat EL 5

[Paul Ramsey]

In addition to adding GEOS 3, you need to complete REMOVE GEOS 2.2.
Are you sure your system is clean? I'm pretty sure I scraped this
version-dependent stuff out of postgis-svn a couple days ago, so all I
can think of is that you successfully built against the new version of
GEOS but your system is still trying to link against the old version
of GEOS.
