Ok, you've already lost me at "change the links in /usr/bin manually", though maybe I can figure it out. But more practically, would I have to do some variable exporting before doing Sage? Or would this alone make everything go solidly? What about for the Fortran part? Or, again, maybe we could provide the 4.2 binary and the gfortran binary directly inside Sage, and use that for all gcc and cc and g++ and whatever else there is that I don't know about... Anyway, changing how we support a particular platform probably deserves more discussion than its received on this thread, so for now I'll wait to see if it worked for you to use this toolkit to build Sage successfully (e.g. 4.6.alpha0) and then maybe I'll take a leap on *one* of my 10.4 boxes to see if it works. - kcrisman -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
