I intend to upload a new octave 3.6.2 with the above change (i.e. recommend atlas | openblas, not the other way round). Since the freeze should happen on June 30th, we need to move quickly, so I will make the upload tonight unless somebody raises his her voice. This upload will also fix the gnuplot Recommends. -- Sébastien Villemot Researcher in Economics & Debian Maintainer http://www.dynare.org/sebastien Phone: +33-1-40-77-84-04 - GPG Key: 4096R/381A7594
