Well, not quite. I think. Exposing that dependency means that
*clients* of cairo require at least pixman 0.12. If cairo re-exports
part of pixman's API, that's a perfectly reasonable statement to make.
The problem is that one picks up this piece of logic without
installing the new cairo that it applies to.

What I don't see is why your build didn't go build a new pixman as a
result of it being out of date. Ordinarily it should have. Did you not
clean or not cvs update x11/pixman? Or is the builtin logic broken?

(Meanwhile I don't see how ABI depends are relevant...)
