It's a conceptual thing: packets with huge dependencies for system libraries like python do a lot of autoprobing (find out if libsomething is there, then build the python wrappers for it). So if Python is built early, it finds less libraries than when it is built late. We maybe need something like a separation into libs and apps, then build all libs first and then all apps. But I doubt it will catch all cases, as there are surely packets out there which are both, lib and app. Could you look how other distributions handle that case? It may give us some hints what to do.
