gem install does not build c extensions

[stephenprater]

I'm not exactly familiar enough with the mkmf variant this uses to further diagnose the problem - but running gem install sender creates an empty makefile which means the C-extension doesn't get built.

(Which means it doesn't work.)

Should be fixed now. I was not seeing the issue as I was using clang rather than gcc by default. Please let me know if there are further problems.
