I suspect you forgot to add EPICS_BASE to the pva2pva/configure/RELEASE
file; you can't just set that in the environment, you need the absolute
path to Base (or to the INSTALL_LOCATION you used when you built Base if
you set that yourself) to be set in that file, or in some other file
that it includes. Note that the EPICS_BASE line should usually be the
last of the variables defined.

It isn't clear which version of the other PVA modules you're using, did
you clone them directly from github too or are you using one of the
EPICS 4 releases? The latest pva2pva probably needs the latest versions
of the other modules although I'm not certain about that.

The EPICS build system is generally very capable, but you have to do
things the way it wants, and module configure/RELEASE files are one
thing it does rely on.
