Comment #2 on issue 1001 by matttbe: Pharo: Moose: unable to get information from Dr. Geo packages. http://code.google.com/p/moose-technology/issues/detail?id=1001
Thank you for this answer but yes, by saying "select DrGeoII-* packages" I means: select these packages and click on the ">>>" button :-)
I don't have this problem with other packages (e.g. with PetitPaser* packages), only with 'DrGeoII-*' packages.
