[ClusterLabs] building from source

[Aaron Cody]

Unfortunately just upgrading to the latest RHEL is problematic for us as we
are working in a highly qualified environment (based around RHEL 7.2), so I
was hoping to get the latest HA stuff by just building it from source...
I looked at the available RPM packages in the RH HA repo but they don't
seem to be the 'latest' ... could you let me know which versions of what I
would need to download and build to get the latest and greatest?
thanks
