Yes. >Or is there more hope here and there's > something I can do to circumvent this error. There is no hope beyond you building sage from source. This is actually much easier than you might think. Do all of the following after login as "manage" and typing "sudo su". 1. Delete /usr/local/sage: cd /usr/local; rm -rf sage 2. Download sage-3.4.2.tar by typing wget http://sagemath.org/src/sage-3.4.2.tar 3. Extract it, tar xf sage-3.4.2.tar 4. Move it to be /usr/local/sage, and mv sage-3.4.2 sage 5. Build Sage -- this will take a few *hours* (no manual intervention) but will work: cd sage; make > > Thanks > Kevin >> >> Wiliam- Hide quoted text - >> >> - Show quoted text - > > > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
