Comment (by warner):

 We've determined that OpenBSD-5.6 has a version of LibreSSL (LibreSSL-2.0)
 that doesn't have ALPN symbols, but doesn't have a version string that
 allows `cryptography` to detect it properly.

 The current release is OpenBSD-5.8, which works ok (thanks to sickness for
 testing this). The operators of our openbsd buildslaves are planning to
 upgrade to 5.8 sometime this summer when some new hardware becomes
 available.

 In talking with the `cryptography` folks, it sounds like they don't have
 any immediate plans to be compatible with the older LibreSSL-2.0 . The
 first step would probably be for somebody to provide them an OpenBSD-5.6
 buildslave (they use Jenkins, but reaperhulk has offered to configure a
 buildslave if someone gives him root).

 https://github.com/pyca/cryptography/issues/1639 is related.
