I don’t know whether this may be an issue related to the metasploit  
framework or to the ruby core directly…

one of the latest metasploit plugins uses the resolv module:

require ‘resolv’

once i run the plugin, I got the following error:

Auxiliary failed: no such file to load – win32/resolv

why is it requiring to use a win32 library while I’m running ruby on  
OSX?

Any help is appreciated
