[postgis-users] Are there any Ubuntu PPAs that serve PostGIS 2.0 beta releases?

The PostGIS nightly builds have been augmented with GEOS 3.3.2 and now 
include the topology plugin. GDAL 1.7.x is still being used from the 
official Ubuntu repositories. The installation steps are now:

    sudo apt-add-repository ppa:sharpie/for-science  # To get GEOS 3.3.2
    sudo apt-add-repository ppa:sharpie/postgis-nightly
    sudo apt-get update

    sudo apt-get install postgresql-9.1-postgis


The build of GEOS 3.3.2 was created using the following steps:

  * Forking the official Ubuntu sources for GEOS 3.2.2.
  * Backporting GEOS from Debian Wheezy to get to 3.3.1 along with 
associated packaging updates.
  * Merging in 3.3.2 from the official GEOS tarball.

This was accomplished by:

    bzr branch lp:ubuntu/geos
    cd geos
    bzr merge debianlp:wheezy/geos
    # De-stage all Debian patches prior to an upstream import
    quilt pop -a
    bzr merge-upstream  # Finds the latest GEOS tarball and merges it in!
    quilt push -a             # Fix any outdated patches.


I had to fix one patch conflict caused by the last command, but otherwise 
everything went smoothly.

GDAL is at 1.9.0 in Debian Experimental, but backporting looks like a 
moderate headache so I'm holding off for now. I may set up a stable build 
of PostGIS beta packages, but it looks like we are pretty close to 2.0 so I 
may wait until the official release. The nightly builds against the SVN 
trunk _should_ be pretty stable in the lead up to 2.0.
