mmm.. you also have /usr/local/lib/libgeos.so.2 I suppose...
This should be fixed when we switch to the C++ library
naming convention following release number, as in
libgeos-3.0.0.so

Another way to handle this could be using -rpath to require
libgeos_c.so to use a specific libgeos.so based on full
path but I don't like being forced to keep libraries in
a specific directory.

In your case the fix should be moving /usr/lib/libgeos.so.2
away (try renaming it to something else)
