It's been a while since I used Chrome like that, but I recall that it 
required a stand-alone exe as well as the gem.

I'd recommend getting Firefox to work with your proxy settings before 
moving on to Chrome, since Firefox should be simpler.

To specify the Firefox installation to use, you need a command like 
this:
Selenium::WebDriver::Firefox.path = "/root/fosiul/firefox.exe"
