[gentoo-user] Trying to emerge rust. It crashed. Now I get circular dependencies. Help!

[Alan Mackenzie]

Hello, Gentoo.

While updating my old machine (a 1st generation Ryzen), I was 42 minutes
through the emerge of rust when it crashed.  This is probably due to the
known hardware error in early Ryzen chips.

So I tried

    # emerge --resume

, which gave me a few lines of emerge messages followed by:

    * Error: Circular Dependencies

    (dev-lang/rust-1.84.1-r1:1.84.1/1.84.1::gentoo, ebuild scheduled for merge) depends on
     (dev-lang/rust-1.84.1-r1:1.84.1/1.84.1::gentoo, ebuild scheduled for merge (build time)

    [ Message copied by hand from old machine to new machine running email ]

I'm not happy about this.  I tried to unmerge that partial version of
rust, but just got further error messages.

How can I unwedge portage in this situation?

Thanks!

Well, I tried

    # emerge -auND @world

again, and it seems to be working, including attempting to build rust
again. 

I'd still be interested to find out what caused the bug in emerge
--resume.
