Does this really work with EAPI=6? I didn't try, but it looks like it
would need an eapply_user somewhere in src_prepare. And, pedantry
warning, there's no such thing as "EAPI 5 or higher." The lawyers will
tell you to do something like this instead (stolen from git-r3):

  case "${EAPI:-0}" in
	  5|6)
		  ;;
	  *)
		  die "Unsupported EAPI=${EAPI} (unknown) for ${ECLASS}"
		  ;;
  esac

That will require an edit for every new EAPI, but prevents weird crashes
from things like a missing eapply_user.
