I got the following when emerging: QA Notice: USE Flag 'macos' not in IUSE for net-dialup/mgetty-1.1.30-r2 QA Notice: USE Flag 'ppc-macos' not in IUSE for net-dialup/mgetty-1.1.30-r2
And a couple more now: QA Notice: Security risk /usr/bin/ct. Please consider relinking with 'append-ldflags -Wl,-z,now' to fix. QA Notice: Security risk /usr/lib/mgetty+sendfax/faxq-helper. Please consider relinking with 'append-ldflags -Wl,-z,now' to fix.
I've looked in ebuild file and found nothing about macos or ppc-macos flags. When exactly did you got these lines: at compile or install? Could you paste a more detailed set of ebuild's output (10-20 lines around QA Notice warnings)?
comment #0: enewuser, enewgroup and egetent in eutils.eclass: "if useq macos || useq ppc-macos ;" macos is not in profiles/arch.list. This is a more general problem: every ebuild using enewuser/enewgroup will print this QA message.
eutils.class have been fixed. now it arch.list contains ppc-macos and eutils.class dumped any reference to macos. comment #1: fixed in mgetty-1.1.30-r3.
