[Solved] Ebuild failed with gnome-shell 3.18

Hie

i post this message to alert some people who want to migrate gnome from 3.16 to 3.18
It can happen that your gdm will not start and when you check your log file you will see a problem with the libgnome-desktop-3.12.0.0 library (segfault blablabla...)

in this case i had to :
- unmerge gnome-shell / gnome-gnome-desktop /gdm (all were in 3.1
- emerge gnome-desktop in the latest 3.16.x version => thus will install library libgnome-desktop-3.so.10.0.0 needed to gnome-shell !!
- unmerge gnome-desktop 3.16 : the library will not be wiped from /usr/lib64 finally you will have libgnome-desktop-3.so.10.0.0 + libgnome-desktop-3.so.12.0.0

finally emerge gnome-shell 3.18.x

normally it should be ok with this.

hope it will help some people.

see ya.
