Bear on me as I am writing this from memory - I already installed firefox-60.4.0 and there is no build.log available now. But it's very easy to reproduce: emerge -C dev-lang/rust emerge -1av =www-client/firefox-60.4.0 dev-lang/rust will NOT appear in the needed dependencies and the build process will stop pretty early saying that "rustc is needed" or something similar. This is not the expected behaviour. The expected behaviour is that the ebuild will take care of the dependencies. Writing from Windows right now, so there is no system info to post - in case you need it, please find it on my other bug reports, e.g.: https://bugs.gentoo.org/675116
Hi, it properly depends on virtual/rust (and cargo, which is provided by rust package) because users may have rust-bin installed. portage does not check if you have virtual/rust's dependencies satisfied at the time of firefox build because you removed rust, not virtual/rust, and broke depgraph for rust and cargo in your example. don't do that. portage assumes you have valid rust implementation if you have virtual/rust installed.
I was wrong about portage, it tries to make sure rust is installed and the dependency is set in a eclass, not in ebuild check eclass/mozconfig-v6.60.eclass in the repo. ya@ws .../gentoo/www-client/firefox:<master> $ sudo emerge -C rust * This action can remove important packages!

Well, I did not have neither virtual/rust, nor dev-lang/rust at the time I wanted to upgrade. I had an old firefox version (48 I think). Strange, but anyway, I just wanted to make sure that rust was not somehow forgotten, as I did not see it being mentioned in the ebuild. Thank you very much.
np, thanks for trying to be vigilant. deps in eclasses are easy to miss, it's not obvious at a first glance. firefox is a VERY popular package, if there was a problem we'd have dozen of bugs withing couple of hours.
