First you need to install the latest version of Sphinx if you have not already done so. You would do something like this:
svn checkout http://sphinxsearch.googlecode.com/svn/trunk/ sphinxsearch-read-only
cd sphinxsearch-read-only
./configure --prefix=/usr/local/sphinx
make
sudo make install
Download and extract the latest fSphinx tarball and install the package.
wget http://github.com/alexksikes/fSphinx/tarball/master
tar xvzf "the tar ball"
cd "the tar ball"
python setup.py install
Make sure you have installed the following dependencies:
[redis][3] which is used for facet caching.
[web.py][4] or the database module of webpy only.
You're done!
