Build dependencies tell the immediately adjacent prerequisites for
building a package. Install those immediate prerequsites (and
all of the other install prerequisites needed by the adjacent vertexes
in the build dependency graph).
That's the algorithm for determining how to build any
I don't know of anyone who has attempted to efficiently
order all builds, not just a single build. There's almost
loops involved, which need to be remedied by using an older
version of some prerequiste in order to build the newer version.
The process I outlined, with multiple passes across a list
of SRPMS, keeping track of the order of successes, will
generate the list you want for the next time you want
to build 3000 SRPMS.
