I'm an idiot. I was stumped when I got this #gentoo error last week, and thought it was a bug somewhere in an ebuild. Got the same error again today and was wondering why they hadn't fixed it yet.
Turns out I have ~amd64 on all the rust-related packages, but forgot about virtual/cargo. The 1.29 version of virtual/cargo doesn't realize that rust-bin 1.30 is sufficient.
I should stop being lazy with investigating errors. 🙄
@ayo you're not alone. It was a couple of days for me to realize it too. Same error, same situation.
@riking Lazy people shouldn't run Gentoo.
@ayo You're getting rusty huh?
