I will test this with at least lang/ruby22 and lang/gcc6-devel when my current build finishes, or sooner if I get impatient. :) > I list both powerpc variants because powerpc and powerpc64 both have > clang problems making buildworld a no-go by default and if gcc 4.2.1 > rejects a port for one it would normally also reject for the other. > There may be other ${ARCH} values that would also be appropriate > because they are also stuck at gcc 4.2.1 .
