Will continue to investigate. Try the following: require 'mkmf' $LDFLAGS << ' -framework Cocoa' have_func('NSApp') # should put 'checking for NSApp()... yes' If it outputs 'checking for NSApp()... no', that would suggest it's related to the problem I described. (BTW, I assume you're running the exconf.rb script via /usr/bin/ruby, yes? What sort of hardware are you on; PPC or i386?) HTH has -- http://appscript.sourceforge.net http://rb-appscript.rubyforge.org
