attempted to build x11-toolkits/gnome-sharp20 version 2.24.1 portrevision 2 with FORCE_MAKE_JOBS enabled in 'make.conf' and build failed. Did 'clean' and "make install MAKE_JOBS_UNSAFE=1" and build succeeded. recommend adding 'MAKE_JOBS_UNSAFE' to Makefile for this port until build issues resolved.
