ld reports undefined symbols in liboil (starting with composite_in_argb_const_src_sse_2pix) and fails to build (log of 'sudo port install liboil' below.) liboil has no dependencies, so I wonder if there is something wrong with the linker or the makefile. I tried sudo port selfupdate and sudo port clean liboil but build still fails.
