[petsc-dev] ccache tips?

[Scott Kruger]

I didn't realize brew put the links in libexec.   I did it manually like 
in this tutorial:

https://software.intel.com/en-us/articles/accelerating-compilation-part-1-ccache

This tutorial discusses the size of the cache.  I made mine too small 
when I first set it up.

I like Jed's mpi method as the things I want cached the most are the 
parallel stuff -- I don't want to cache the serial externalbuilds.
