Do you have two versions of GEOS on your system?  It looks like you may
have installed 3.3.3 and then also 3.3.5; perhaps this is confusing to
the configure script.

I do this by compiling each of the libraries in /usr/local/src/library-name,
so first I download the latest source, unpack them in /usr/local/src, and
build from there, like this:

cd /usr/local/src
tar xzf ~/proj-4.8.0.tar.gz
cd proj-4.8.0
./configure
make
make install
/sbin/ldconfig

With the default configure, it may help to have a file
named /etc/ld.so.conf.d/local.conf
containing the one line
/usr/local/lib

then

cd /usr/local/src
tar xjf ~/geos-3.3.5.tar.bz2
cd geos-3.3.5
./configure
make
make install
/sbin/ldconfig

and

cd /usr/local/src
tar xzf ~/gdal-1.9.1.tar.gz
cd gdal-1.9.1
./configure
make
make install
/sbin/ldconfig

then install PostGIS the same way.
