Description Johannes Willem (Hans) Fernhout 2019-03-18 12:21:22 UTC 
dev-lan/rust-bin provides also cargo functionality, but with the default use flag -cargo it pulls in dev-util/cargo as a separate package:

--/--
# emerge -va rust-bin cargo

These are the packages that would be merged, in order:

With the cargo flag set emrge goes well:

--/--
# emerge -v rust-bin

Solution would be to remove the cargo use flag for dev-lan/rust-bin.
Comment 1 Johannes Willem (Hans) Fernhout 2019-05-13 05:26:39 UTC 
The cargo use flag seems to have been removed in rust-bin-1.30.1-r1 and later:

-/-
# cd /usr/portage/dev-lang/rust-bin
# grep IUSE rust-bin-1.*d
rust-bin-1.29.1-r1.ebuild:IUSE="cargo clippy cpu_flags_x86_sse2 doc libressl rustfmt"
rust-bin-1.29.2-r1.ebuild:IUSE="cargo clippy cpu_flags_x86_sse2 doc libressl rustfmt"
rust-bin-1.30.1-r1.ebuild:IUSE="clippy cpu_flags_x86_sse2 doc libressl rustfmt"
rust-bin-1.31.1.ebuild:IUSE="clippy cpu_flags_x86_sse2 doc libressl rustfmt"
rust-bin-1.32.0.ebuild:IUSE="clippy cpu_flags_x86_sse2 doc libressl rustfmt"
rust-bin-1.33.0.ebuild:IUSE="clippy cpu_flags_x86_sse2 doc libressl rustfmt"
