You need to pass `--enable-cxxstd=11` when configuring to build in
c++11 mode. The configure help makes it seem like the standard will
be auto-detected (based on, say, your compiler version), but in
reality it just defaults to 14.

Are you quite sure? I don't think that is true.
On the other hand, gcc 4.3 is long before C++11,
so no modern version of OIIO is expected to work with gcc
older than 4.8 and C++11. That may also be true of OpenEXR,
I'm not sure without checking.
I think
one of my problems may be that because the latest
version of OpenEXR requires c++17 (gcc7), I ended up
with two different compile environments, since all the
other official repos for my RHEL release (7.4) were
compiled under gcc 4.3. Tomorrow, I'm going to go
back and find an OpenEXR version that compiles under
4.3 and try the whole thing again. Now going on 3
days of solid work just to get it compiled.

I don't understand... if it's a
transitive dependency via libavcodec, shouldn't it
have been automatically installed at the time that
libavcodec was installed or built?

The dependency on opus is only a
side-effect of the way the libavcodec
you're using was built. Opus should
definitely not be considered a dependency
of OIIO.
Luckily, ffmpeg is pretty straightforward
to build as a set of self-contained static
libs (I believe it does so by default).
