I've tried to run update today and got problem with dev-util/cargo-0.29.0. It refuses to compile.
Here's what I get:

As far as I understand, this is needed to build newer version of firefox. Any recommendations? |

| Same here... Seems we hit this bug. I masked dev-util/cargo-0.29.0 as a temporary fix. |

Yes, but you can check if virtual/rust-1.28.0 is stable now

Try with
| Code: | # emerge -u dev-lang/rust-bin
# eselect rust set rust-1.28.0
# emerge -u =cargo-0.29.0 |

| @fedeliallalinea Turns out I needed to depclean first. Had rust-1.25.0 installed, and I think that was the one that was causing the problems. |

If you use eselect for set rust-1.28 you can depclean after update

| What fixed it for me was to recompile those rust packages and 'eselect rust set rust-bin-1.28.0' rather than rust |
