This is an auto-filled bug because net-print/cups calls ar directly. The issue was originally discovered on x86, but it may be reproducible on other arches as well. Attached build log and emerge --info. NOTE: This issue has been reproduced by setting the AR variable and by removing the /usr/bin/ar binary.

still valid with 2.3.3_p2-r2?
