aircrack-ng ebuilds are wrong in emake call in src_install function. At least 3 binaries of this package needed for use aircrack-ng (i.e. airodump) aren't be installed (they should be in /usr/sbin/. One possible solution is change emake call in src_install adding "install", like this: emake \ prefix=/usr \ docdir="/usr/share/doc/${PF}" \ mandir="/usr/share/man/man1" \ destdir="${D}" \ ${target} \ doc \ install || die "emake install failed" Changing this all binaries will be installed. Reproducible: Always
USE="wifi" emerge aircrack-ng and you'll have your binaries
oh, I didn't see it, thanks you.
