Non-issue. APT, remember?

To be honest, I'm substantially more interested in the ability to do
this on the local system. There are, as a rule, not all that many
packages required to build the system. A chroot is nice, but doing it
outside of one could be more useful.

First of all, a speed tip - make libtricks send it to a _file_. Both
simplify parsing and increase speed quite amazingly.
I think that while this is a nice idea, source depends added by hand
will be a lot more useful. There are some definite problems - for
instance, packages which will build just fine without emacs installed
but more completely with, or ditto makeinfo.
