Hi. I don't check MULTIPLICITY knob in port's config, but after compiling on -stable I got ... useithreads=define, usemultiplicity=define ... Compile-time options: HAS_TIMES MULTIPLICITY PERLIO_LAYERS ... lines. Perhaps MULTIPLICITY_CONFIGURE_OFF= -Dusemultiplicity=n should be added to Makefile -- http://ache.vniz.net/
