Good, I will add that solution to the FAQ then shortly.

Good point.

Well, that has been more or less the way it used to be. We used to
provide binaries as a convenience since the vast majority of people
used to build from source. That has changed now and we need to deal
with that.

Well, that would increase download size for everybody which is
something we have been trying to shrink lately. I am not sure how we
would do provide the right ATLAS dynamically - Debian's ATLAS
struggles from the same problem, so if you have any ideas [or even
better code] in that direction I would be very glad to hear about it.

No problem, that is what we are here for.
