The epicsVersion.h header does exist at the location mentioned

$ ls /home/mdavidsaver/work/epics/base-git/include/epicsVersion.h

The bundleCPP Makefile wasn't intended for or tested with more complex configurations like this, so I'm not surprised it doesn't work. You may even have to configure the pvaPy module by hand — its README.md explains how to do that by hand or use its make configure target but the latter might not work with your 'install everything into a single location' configuration.

When I was fixing a few things in pvaPy some months ago, the tests in autoconf were implemented quite sloppy, and printing misleading messages. Please confirm what the test is actually checking - obviously not the existence of that file...

The epicsVersion.h was a typo in the autoconf script which has since been fixed (on the master branch). Additional discussion on other aspects of this issue is occurring in epics-base/bundleCPP#3 and epics-base/bundleCPP#4. I haven't checked yet whether INSTALL_LOCATION works with the pvaPy build so I'm not closing this issue yet.
