The error, while mixed in the backtrace seems clear to me: the usage of
native extensions (C) with JRuby is not recommended.
Also, it is failing to find a suitable compiler ("cc").
If you still want to use JRuby, probably you should want to obtain a
compiler for it. I heard that someone managed to use RubyInstaller DevKit
with it, but I haven't tried it out.

If your version of JRuby is newer than the one indicated there, perhaps you
don't need to compile JRuby yourself.
YMMV specially considering win32-api gems are not suitable for JRuby.
Developers are working on port it to use FFI instead. You can also reach
the Watir guys to figure out alternatives.
Hope that helps
