It is strange... mcqd was merged in the trac ticket #16083 but apparently the list of optional packages was not updated. The same thing happens for pip (trac ticket #16479).
Right now, you can do: 1) download mcqd-1.0.tar.bz2 which is linked from http://trac.sagemath.org/ticket/16083 2) put it in SAGE_ROOT/upstream/ 3) run "sage -i mcqd" Vincent 2014-08-16 0:42 UTC, Peter Mueller <ypf...@googlemail.com>: > The changelog for Sage 6.3 says that MCQD can now be used to compute a > maximum clique in a graph.

I don't see it among the optional > and experimental packages. > > -- Peter Mueller > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-support+unsubscr...@googlegroups.com. > To post to this group, send email to sage-support@googlegroups.com. > Visit this group at http://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
