I find it amazing too that I haven't run into the issue or heard from
anyone else. I have a couple build environments that I thought were
minimal, but they clearly must have had the openssl dev packages
installed or I would have seen it.
Anyway, I agree with Yann, that there's no rush on getting the fix in
for this release. Now that we know how the issue manifests itself,
it's pretty easy to identify.
