sys-apps/findutils contains some prefix-specific thing fixing a problem that's now resolved upstream. Or so I'm told by posters in bug #469206. Anyhow, everything seems to go correctly if I apply a change like the enclosed patch; otherwise, the ebuild dies in src_prepare. The problem only manifests in a prefix for reasons that should be obvious. Reproducible: Always
Created attachment 360740 [details, diff] patch to fix findutils
Created attachment 360742 [details] build.log from failling findutils merge attempt (without the enclosed patch applied)
Since the old bug caused a build failure and the generated gnu find with the enclosed patch applied seems to do gnu-find-ey things OK, I am reasonably confident this really is fixed upstream.
per the original bug this is correct. patch accepted, thanks Gregory
