Hi Markus,

your "PS" are the important bits. Currently GeoCouch doesn't work with
the master branch of CouchDB (which will become 1.3.x). You have to use
the 1.2.x branch (or the 1.2.0 release). In order to get GeoCouch to
work with that, you also have to use the correct branch of GeoCouch,
which would be the "couchdb1.2.x" branch.

Cheers,
  Volker
