It did have it, at least the RPM db thought it did - which confused me
for a while, but it was actually linking against the system libvpx.so
Not sure what happened there, but a clean rebuild seems to have resolved
that, I think.

The yum error message is a little bit confusing. This is not the first
time I have wished that yum/dnf/rpm would be more clever about managing
dependencies so one could more easily link against different versions
all living in the same repository. Maybe I missing a trick there?

Cheers
Antoine
