How can thetango know that perl-Foo will be providing perl(Bar) which perl-Baz BuildRequires? E.g. how can any automatic provides be guessed by thetango? A not-too-far away goal is to have a perl()-like system for python and other languages, which means more and more BRs depending on virtual automatic provides that you can only detect after a build, not before. I guess that if thetango cannot compute the depdency then it probably gets discarded to at least get some better ordering, but the final build will still need a brute force iterative approach. > thetango attempts to resolve the build problem by taking a set of SRPMS and > building build trees by evaluating the dependencies between the potential > resulting binary RPMs, and determining the build tree for individual SRPMS. > > * I have not put this in source control yet.
