Somebody should post a new spkg. Then I'll test it on Itanium and see whether or not it works. If not, then it doesn't go in, but we can at least report the problem again to the GAP list. > > Dmitrii > >> >> -- William > > -- > To post to this group, send email to sage-support@googlegroups.com > To unsubscribe from this group, send email to > sage-support+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/sage-support > URL: http://www.sagemath.org > > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org
