Just as the new revdep-rebuild starts, it shows this warning: * This is the new python coded version * Please report any bugs found using it. * The original revdep-rebuild script is installed as revdep-rebuild.sh * Please files bugs at: https://bugs.gentoo.org/ In the last line, "Please files:" should be "Please file".
Fixed in commit: https://gitweb.gentoo.org/proj/gentoolkit.git/commit/?id=e9445aa398126c24c729cfb1e0d488d9b0db45ab
