[Observium] No memory pools detected for OSX hosts

Hi there,

I'm running Observium 0.16.7.8003 (stable) for monitoring OSX hosts which is working great, except no memory pools are being detected for any hosts apart from "Swap space".

Memory for OSX hosts did work previously, but after I mailed in re: "Incorrect free physical memory for Unix hosts" and Adam A. made a change, the memory pools have disappeared.

What's the best course of action?

Many thanks

Olly
