Your problem is that bundle is trying to install EventMachine with it's C-bindings and it's not finding the libraries that EventMachine needs to be built. That's what that first line in the error message is telling you
Since you're on Windows, this complicates things somewhat, but they have a good guide on installing EventMachine on Windows: https://github.com/eventmachine/eventmachine/wiki/Building-EventMachine-with-SSL-on-Windows You'll probably need a few other components installed, but look at the guides from EventMachine wiki and just Google around for what other people did.
