--- Comment #7 from Peter Schiffer pschiffe@redhat.com --- Hi Douglas,
ah yes, I know about this error and I've already checked it. In this case, this shouldn't be a problem because the gid is not changed, the bsd-mailx binary doesn't have suid and sgid flags.
This error was introduced by 03-Base-fixes-2.patch. I don't think that it's realy worthy expanding the for loop applying upstream patches for better debugging things like this (which is probably only this one error, considering the bsd-mailx is not actively developed any more).
