Hi
first install geos library using Ubuntu software center (libgeos, libgeos-dev)
then download gdal source and configure it:
./configure --with-python -with-geos=yes
then
make
sudo make install

If that doesn't work give me a sign, I'll publish more detailed instructions.

Good luck!
Anton

ps. I have Natty, Python 2.7 and GDAL with support of HDF4 and GEOS. Everything works perfect.

How do you install GDAL with GEOS and the Python Bindings on Ubuntu
Linux Natty Narwhal 11.04?

I've Googled an awful lot and tried heaps of suggestions most of which
I'm afraid I can't remember.  Presumably my system is now in a horrible
mess.  I remember installing umpteen different versions of Python, for
example.

Somehow I managed to get enough of GDAL and Python to work to use
gdalbuildvrt and gdal2tiles.py.  But now I want to do something like:

ogr2ogr -s_srs EPSG:2193 -t_srs EPSG:2193 -f "GeoJSON" -clipdst
18785164.071364913 -5009377.0856973119 20037508.342789244
-3757032.814272983 doc-campsites-clipped.json doc-campsites.shp

which responds with hundreds of lines of "ERROR 6: GEOS support not
enabled."  Leaving out "-clip dst", as below, works though.

ogr2ogr -s_srs EPSG:2193 -t_srs EPSG:2193 -f "GeoJSON"
doc-campsites-clipped.json doc-campsites.shp

I probably tried using the Ubuntu Software Centre.  I remember doing
something with FWTools, reluctantly, because it's out of date.  I
remember building lots of stuff from source.  I added the
ubuntugis-unstable repositry and did "apt-get update".  My hopes were
raised when "apt-get install gdal-bin" didn't fail, but then "apt-get
install python-gdal" responded with

The following packages have unmet dependencies:
  python-gdal : Depends: python (< 2.7) but 2.7.1-0ubuntu5 is to be
installed
E: Broken packages

Which is how I ended up installing (maybe even building) earlier
versions of Python.

Many thanks,
Duncan
