The :problem is with the extension where a DLL is to be built (Win32API, socket :...). 'dllwrap' isn't able to create a :dll for the extensions. Please, see problem description below. I've :submitted it as a bug in the Ruby Bug tracking sys but it would be great :to hear if someone have managed the compilation. I've searched for docs on :dllwrap but haven't found any. I've already fixed it. Check the latest CVS(ruby_1_4 branch). -- eban
