It doesn't depend on gdk-imlib at all. Only png2/10 (and only
because gtk1 needed it to be so).

If this conflict came from png3/png-dev, I'd find it easier to
agree with that claim.

Well the latter just makes it "stable" ;-) I guess I don't properly
understand the deep link between the png packages and the gdk-imlib
ones, as affects packages that don't care about gdk-imlib at all.

(the former I noticed after firing off this report)

Yeah. wx2.6 is out, so the long term plan is to kill wx2.4, but
the same caveat applies.

In this case I just need to fix the build-dep from png10 -> png12,
(for the bits I'm responsible for) but I guess I missed the memo
that we were rolling on that this week. I'm not unhappy that it's
happening, just surprised at how...

thanks!
