Hi, I think the one current thing holding up SAGE-2.9.1 is that Martin's separation of m4ri out of the sage core library is unfortunately completely broken on all flavors of OS X. Any call to it segfaults. E.g.,
sage: span(GF(2), [[1,2,3], [2,2,2], [1,2,5]]) Program received signal EXC_BAD_ACCESS, Could not access memory.
