Hi Miles and Barak, I noticed that the FTBFS is caused by a single failure inside build time tests. Did you tried tracking this down? While I do not know this specific package and can't estimate myself in how far this test is important it could be that deactivating this test might be a sensible course of action. "Div" somehow smells like possible floating point representation and might not be a real error but possibly a wrongly defined test case. Could you please check this.
If you agree that this test should be excluded and just do not have time to do the actual work I'd happily help with doing a team upload. Kind regards Andreas. -- http://fam-tille.de
