<snip> * If you upgrade to >=sys-apps/coreutils-6.7-r1, * you should re-emerge ruby again. * See bug #159922 for details </snip> Seriously, with 6.9-r1 being stable (since June 2007) and the only coreutils version in the tree, this warning is just confusing.
Agreed, and this message was always a kludge to work around the issue. I've just removed the message from ruby-1.8.6_p111-r1.
