Yet another fault...
I have successfully prepared gtk+3 package set on my home cook. I moved them from wok-undigest to wok.
On the server side cooker can't find packages: atk, pango, cairo and cairo-gobject:
(I think, it need *-dev versions of them).
But these packages are successfully cooked and we can find them in the cooking mirror and in the cooking cook reports:
and so on...
So, please, update cooker database, or anything similar (sorry, I don't know the real source of problem).
