builderCI[1] (which you can easily use to test using metacello/seaside!)
uses a statically compiled SqueakSSL plugin[2] that is also used in our 
5.0 All in one[3]. You can find the binary plugin at github[4].

I presume the reason it is not in Eliot's bundle is that I haven't yet
figured out and told him how to do the “compile SqueakSSL statically
against LibreSSL” thing in his build setup. Mea culpa. Please be patient on
this one, I'm on vacation currently…
