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 single package. 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. 73 de Jeff
