Excellent.

I'm sure building like you want (against standard Gentoo packages) would be possible *with sufficient effort*. > If you're not a Gentoo user, what do you use? On a daily basis I use: * OS X * Ubuntu Linux * Debian Linux I regularly build SAGE on OS X intel and powerpc, Ubuntu 32-bit, Debian 32 and 64-bit, Mandriva, Fedora, and SUSE. And if you're curious, I also regularly use both vim and emacs, and all three of Firefox, Safari and Opera. > At some point I'll probably become a Gentoo developer, assuming: > > a.

Gentoo doesn't die from internal politics before that. :) :-) Thanks; keep me posted. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
