For the past several weeks I've found it impossible to emerge sage from the sage-on-gentoo overlay because the ebuild for sage-5.2 (~amd64) and sage-5.3_beta2 (masked) requires ~dev-python/networkx-1.6. However networkx-1.6 is not in portage any longer; networkx-1.2 is in the overlay and networkx-1.7 is in portage.
sage-5.1 had a networkx-1.6 specific patch but I don't see any patches in sage-5.2 that are networkx specific. Should I copy the sage ebuild into my local overlay and change the dependency to networkx-1.7? I'd be glad to be warned if any one knows of any problem I would encounter before I invest the time to try emerging sage to use the newer version of networkx. I also was wondering why dev-python/networkx is required; I thought that networkx was integrated into sage?
