I have been having this problem on windows 7 where I have installed JRuby, sometimes when I try to install a regular Ruby gem instead of something for JRuby I get an error message that seems to indicate it thinks it''s for JRuby .. Below is an example. If I was going to install the gem to JRuby I would type jruby -S gem install watir --no-ri --no-rdoc, but I tried to install it to the other Ruby: gem install watir --no-ri --no-rdoc C:\Users\lguild\Downloads\devkit>gem install watir --no-ri --no-rdoc Building native extensions. This could take a while...

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. http://jonforums.github.com/ruby/2010/11/30/devkit-jruby-c-extensions.html 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.

I got it to work using the pic gem, I was trying to install watir on my regular ruby and not jruby. Even though the error said jruby, I did not invoke jruby gem.
