0:07.12 ERROR: Rust compiler 1.27.1 is too old. 0:07.12 To compile Rust language sources please install at least 0:07.12 version 1.28.0 of the 'rustc' toolchain and make sure it is 0:07.12 first in your path.
I'll adjust but please notice that oldest version in repository is virtual/rust-1.29.1 which would be enough and according to Gentoo policy, in this case we don't need to "enforce" a newer version.
I see, but for a regular user it's better if emerge firefox simply works ;)
