Title: Optimize gem loading time

Took about 0.5 seconds to load this gem due to a system call that checks if ruby is installed. Instead of loading the entire ruby environment to verify the existence of a ruby executable, I had it check the version. I couldn't get your tests to run, but I think this replacement should be sufficient.
