I'm trying to install Gentoo on an old laptop.

I have arrived at the step to run grub-install and it failed. Turns out the grub installation was not successful. Through out the installation process, I think I missed several signs that some previous step has failed.

If I read the error correctly, it says something like "because some of my selected package requires rust, and rust needs my CPU to support SSE2, the installation fails."

So my questions are:

  • How do I unselect packages that cause the installation problem(s)?
  • I can do my installation without GNOME. Is there a way I can install a systemd-boot setup without rust?
  • If I cannot use systemd, then how do I revert my installation enough for a sysinitv installation without redo all my installation procedures?


Contexts:

If I now run:
Code:

emerge --ask --verbose @world


I will get these error messages:
Code:

I think it is the gnome-base/librsvg package that requires rust to compile, but there are other packages that may require rust.
You can install the precompiled dev-lang/rust-bin instead of dev-lang/rust.
