I suggest you take a look at 
Sumo from HZB (BESSY-2), it's the closest equivalent to automated package management for EPICS that I've come across, but it installs everything from source. Once it has a database of your support modules, you just have to give each IOC a configure/MODULES
 file, which tells Sumo what support modules and versions the IOC needs. Then it can download, patch if necessary, configure and build them all from source, and configure the IOC's configure/RELEASE file, all in a single command. If any subset of those modules
 have already been built with the same set of upstream dependencies it will reuse those and only build the extra modules that are needed.

The APS-U Accelerator Control system IOCs will be built using Sumo, so far it Just Works™.
