This appears to be a recommendation (requirement) from the project. N-1
to bootstrap.

However, since you're poudirere-devel you might be able to take
advantage of binary downloads PACKAGE_FETCH_BRANCH in poudriere.conf.

You'll still have cases where you need to rebuild because of missing
deps where builders are out of sync with the latest ports tree.  I think
some of those are trying to addressed here to loosen the exact
requirements of what poudirere/pkg things needs rebuilt.

What I've done in the past to semi-workaround this is to dial the tree
back to the commit the builders last built on.  Sometimes this can be a
tricky thing to pin down.
