I'm fine with requiring some Python be installed as a prerequisite for building Sage. Python is a fine language for writing system/build system scripts. Several of the Sage components use Perl (NTL and Pari), so some systemwide Perl is a prereq for installing Sage. Requiring some Python is just as reasonable as requiring some Perl, which we already do. -- William > > Dave > > > -- > 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 > > To unsubscribe from this group, send email to > sage-devel+unsubscribegooglegroups.com or reply to this email with the words > "REMOVE ME" as the subject. > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org -- 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 To unsubscribe from this group, send email to sage-devel+unsubscribegooglegroups.com or reply to this email with the words "REMOVE ME" as the subject.
