[gentoo-user] Problem with world update after the clang category change

[Arthur R.]

Hello everyone! When I'm trying to update world with latest sync, I'm 
getting this error:

!!! Ebuilds for the following packages are either all
!!! masked or don't exist:
cross_llvm-x86_64-w64-mingw32/clang-crossdev-wrappers
Is this normal behavior? Can I continue with the update? thanks for the 
answers in advance :)
