Ok, we reinstalled ckan with the mentioned branch. But get the following
error if we add the needed plugin dataset_extend_map
(w/o this paster starts CKAN - but of course w/o spatial search) :
(pyenv)bash-3.2$ paster serve development.ini
Traceback (most recent call last):

Any clue what's going wrong ?
