Thanks for the log; one place there looks suspicious, and probably results in your errors
[spkg-install] [9/30] Linking static target extern/agg24-svn/libagg.a [spkg-install] ar: extern/agg24-svn/libagg.a.p/src_agg_bezier_arc.cpp.o: plugin needed to handle lto object So it's probably ar which needs to be replaced by gnu-ar, don't know how, though: https://gcc.gnu.org/legacy-ml/gcc-help/2016-01/msg00061.html If you can manage this, and rebuild, fine. If not, can you try merging the branch pull/3/head of https://github.com/cxzhong/sage pull/3/head and see if it builds. This is an update of matplotlib and its deps, hopefully it will fix this all.
