Could you please check whether the license for the CSIRO library [1] is DFSG-compatible? There has been some discussion about this in Bug#500687 and in the debian-gis mailing list [2] [1] http://plplot.svn.sourceforge.net/viewvc/plplot/trunk/lib/nn/README [2] http://lists.alioth.debian.org/pipermail/pkg-grass-general/2008-September/003209.html Thanks, -- Rafael
