arping 2.x is for libnet 1.1.x. For libnet 1.0.2a use arping 1.x !!! and because of this reason you get an error when you try to emerge arping 1.x while libnet 1.1.x is installed (default in new rsync: arping1.0.6-r1 && libnet 1.1.0-r3) Reproducible: Always Steps to Reproduce: 1. emerge net-libs/libnet ( /usr/portage/net-libs/libnet/libnet-1.1.0-r3.ebuild ) 2. emerge net-analyzer/arping ( usr/portage/net-analyzer/arping/arping-1.06-r1.ebuild ) Actual Results: arping.c:63:24: libnet-1.0.h: No such file or directory Expected Results: no error ;) look at the homepage for output-details
