Hi Oz,

You are not doing anything wrong, but I am not sure we still have anyone to
maintain a deb for Pysparse. The one you have is for an outdated version of
Pysparse. You will have access to the find() method if you use the svn
version of Pysparse. Your script works as is for me.

Cheers,
Dominique
