==Gramps only properly generates .gv output format on GraphViz based reports==
'''GraphViz package installed ''' but you cannot use all available output formats for Gramps' reports based on GraphViz , because generated files are missing or not very nice. Using the [ http://www.graphviz.org/download/ last available GraphViz package ] for your distribution may often fix some issues. Also, PDF (GraphViz) or PostScript issues could be related to your [http://cairographics.org/ cairo library] (or python-cairo).
