adding a /usr/bin/cargo -> /usr/bin/cargo-1.32.0 symlink fixes the problem
Hi, it's a known problem after upgrading from certain versions of rust which did not provide cargo, read the postinst message. cargo is now installed from dev-lang/rust{,-bin} instead of dev-util/cargo. This might have resulted in a dangling symlink for /usr/bin/cargo on some systems. This can be resolved by calling 'sudo eselect rust set rust-1.32.0'. *** This bug has been marked as a duplicate of bug 671182 ***
