I have made an inline instalation of sfepy-2013.3 on fedora22 , I run the tests and I have only 3 failed, they maybe related to the parallel option since I don't have instaled that option. I have python 2.7.10, mayavi 4.4.3, VTK 6.1.0, Qt 4.8.6 Either on the python or ipython window when I try to import:

*from sfepy.postprocess.viewer import Viewe*r I get the following message, *cannot set toolkit to wx because it has already been set to qt4* and of course any postprocessing will fail
