Exactly. We are just trying to do an initial triage at the moment, so
that the update to boost-1.37.0 does not leave all these deps
broken over the holiday break.

We're almost there!

I did the initial list with repoquery. I see now that there are python
scripts to do this more accurately. (Will use these in the future,
would be great to have this functionality directly with the basic
tools.)
