If I understand correctly and you are saying that upstream are changing
interfaces (structs, function arguments etc) without bumping the SONAME
in an appropriate way then indeed that is a mistake.
If upstream are unwilling/unable to manage the SONAME properly then, at
least in the Debian/Ubuntu ecosystem, it falls to the package
maintainer to do so and bugs should be reported if they miss something.
I'd bet (but don't know) that the same is true in the Fedora ecosystem.

As far as Bill's problem goes if he is both building and running on
Ubuntu 14.04 that ought to be sufficient -- that's a self contained set
of dev and runtime packages.
