Well, maybe.

For some reason, neither libpng nor libjpeg was installed
in my rootfs.

I'll do a clean build and look more closely the next time.

I'm also confused about how things linked in the first place.

Both of those libraries must have been present during the
configure and build steps, but neither made into the
filesystem and I'm not sure why.

In my first attempt to pull in the gl-plugin, I added it
via local.conf. Perhaps that's the root cause and I'll
try to confirm things...
