You're not the only one, I've seen this since 7am on the 28th(GMT). I
was hoping something else would be updated that would then permit the
update.

Dear all,
I am new to Gentoo and I installed it just two days ago.
If I run `emerge --ask --update --deep --newuse @world` I ge the
following warning:

My guess is that `dev-util/mesa_clc` has that LLVM_SLOT="20 -18 -19"
that requires libclc version 20; yet, I wouldn't know how to solve
this, therefore I am asking here.
Why do I get this warning and are there any possible solutions for this?
Thanks.
