The solution was changing default system-vm with "java-config -S 1"
 
 
sandro@ci74771ht ~ $ eselect java-vm list Available Java Virtual Machines:   [1]   oracle-jdk-bin-1.7  system-vm   [2]   oracle-jre-bin-1.7 

mmm actually the wicd gui is a bit 'ugly.
Anyway, I tried again by adding the global USE "networkmanager" and this time I have not had any problems with dependencies (I'm using "Hardened").

Thank you :)

Forgive me if I still write in this thread I thought was resolved; 
Unfortunately (I use Funtoo "stable"), you are just repeated incidents at kernel level. 
So I exposed the kernel 3.15.1 and compiled. 
Now after more than 10 start-ups of the system, I have not encountered problems. 
So at this point I think they have improved their situation at kernel level. 
I hope this information can help those who found himself in the same situation ...... 
and Funtoo never dies .... : -P   :) :D

Since it is a duplicate of a solved thread, could you delete that ?
Thank You

Ok, I think I have achieved significant results.
Networkmanager now works.
Remain unmet dependencies but only 2:
