Those who have problems because of that, use chroot builds; cleaning out
every usage example in documentation may be insanity.

If only it weren't a ton of not-so-useful spam... Most of the time
"missing optional dependency" message is not in the last 10 lines (even
more so - not in the first 10 lines). So it is impossible to see this at
glance; and if you are going to read carefully, you can just click the
Hydra build log link.

What can be a nice idea, though, is sending out "disappeared run-time
dependencies", checking by name (without hash and version)...
