Description Bernardo Costa 2015-12-11 09:42:11 UTC 
After an upgrade of python, with corresponding python-exec upgrade, emerge suggests to do emerge @preserved-rebuild. All packages I had installed successfully recompiled, except for matplotlib, witch failed with

                        * The following required packages can not be built:
                        * gtk3cairo

After a bit of research, recompiling dev-python/pygobject solved the problem. It is not clear how portage should know about this breakage, but I hope at least people searching for a solution will find this bug report here.

Reproducible: Always

Steps to Reproduce:
1. Upgrade system which includes dev-lang/python, dev-lang/python-exec and matplotlib
2. emerge @preserved-rebuild
Actual Results:  
Recompilation of matplotlib fails
