[gentoo-user] Update to dev-libs/icu-51.1 results in borked Dolphin

[Mick]

Updating dev-libs/icu-51.1 uninstalled /usr/lib64/libicuuc.so.49.1.2 and when 
I try to start Dolphin I get:
==================================================
There was an error loading the module Dolphin View.
The diagnostics is:
Cannot load library /usr/lib64/kde4/dolphinpart.so: (libicuuc.so.49: cannot 
open shared object file: No such file or directory)
==================================================

Should revdep-rebuild have picked this up, or would this only work if  
/usr/lib64/libicuuc.so.49.1.2 had not been removed yet?

Trying to rebuild dolphin gives:

==================================================

Time for a bug report or am I missing something?
