 Using -> as an indication of dependency, it turns out:

 python26 -> tk -> Xft2 -> xrender -> xorg-libX11 -> xorg-libxcb -> xorg-
 xcb-proto -> python26

 So there is a circular dependency making everything in the chain and
 anything that depends on something in that chain uninstallable. In my
 case, that is git-core.
