gcc required due to vmstat add_runtime_dependency

[jpcarey]

the add_runtime_dependency for vmstat requires that the system this gem will be deployed to must have a gcc compiler in order to compile the vmstat binary. This is an annoying dependency, and is required even if the vmstat package is available on the system.

@jpcarey @analytically Sorry for the late response. I agree with it being a pia, and would be open to pulling it if a better solution is known otherwise I am not sure what the best course of action is.

It's kinda problematic dependency...
Perhaps moving vmstat to different plugin might be right solution?

apt-get install build-essential in debian will enable installing memory-checks plugin...

I'll accept a PR removing the dependency and detailing the vmstat installation for check-ram.rb. Would it also be possible to add a check to check-ram.rb?

@analytically sorry I must have missed the email. I have yet to find a better solution with a ruby implementation and I dont think we can get around that. What I suppose we could do is make it a development dependency, add a check to the plugin, and detail the unique install instructions...

Sounds good! And add explanation in CAPITAL in plugin description...
