Openafs large file support don't work because of wrong econf parameter in file openafs-1.4.0_rc3.ebuild. This fix the problem for me. econf \ $(use_enable pam) \ $(use_enable debug) \ --enable-largefile-fileserver \ ${myconf} || die econ Reproducible: Always Steps to Reproduce: 1. 2. 3.
Indeed, --enable-largefile as in the openafs-ebuild is wrong.
Change applied in openafs-1.4.0_rc8. Fixed
