Oh, they've finally shipped?

Yeah, it looks for /usr/lib/libstdc++.so.8, but what you have, since you
are running NetBSD 8.99 is /usr/lib/libstdc++.so.9, so that explains this.

Dirty hack, since the two versions of the libs should be close enough,
is to symlink the non-existing one to the existing one and nuke that hack
once you're done building rust. Worked for me on the Pinebook.

Kind regards,
            Alex.
