You can:

begin
  require "devkit"
rescue LoadError
  # ...
end

A proper installation of DevKit will place a "devkit.rb" in the
$LOAD_PATH, you can use that to detect if is present or fail.

I just sent you a pull request with minor changes.

This is awesome! thank you for taking the time to work on this!

I noticed that with every gem the compilation of the executable is
triggered, perhaps we would like to cache the executable inside the
Gem datadir and compile only once?

I'll investigate that a bit more and get back to you, in the
meantime... welcome back and thank you!
