Are you still seeing this with recent Rust versions?
I just ran into this with current ebuild's but found my install had broken packages as found with qcheck. I believe remerging autoconf was the fix in my case.
The original reporter was using a macOS prefix, can you give me your emerge --info?
I believe prefix PATHS were fixed, please reopen if you still hit it.
