Actually this is not a good idea because then, every time you update your system, you get the slow version. In my opinion the fact that guix makes it easy to build a package on the user machine is really a key advantage over other package managers/distributions, for a few, somewhat special packages, ATLAS being one. It would really be a pity to give up such nice a feature to spare some build time (ca. 10 min. on my system from 2007). Regards, Fede
