I followed the following tutorial to build sage on debian. When I run "debian/rules build-dep reset" inside the sage directory that I cloned from git, I get the following output:
mk-build-deps make: mk-build-deps: commande introuvable debian/rules:149: recipe for target 'build-dep' failed make: *** [build-dep] Error 127
I have debian 8.0 (jessie). I have already installed build-essential and make. In French, "commande introuvable" means "nowhere to be found". I guess in English, it would be "command not found", wouldn't it?
