Do the Curl developers support LibreSSL?

[ryandesign (Ryan Carsten Schmidt)]

It will apparently be fixed in 7.60.0. See ​https://github.com/macports/macports-ports/pull/1671#issuecomment-384880683

Unfortunately, I have to report that build fails with libressl 2.5.5:

This is on 10.13.4 with libressl @2.5.5_0.

I would like to switch to libressl-devel, but libevent and py27-cryptography are still not fixed for libressl 2.7.2, so I cannot do it yet. I am not sure if making curl to build with libressl 2.5.5 is justified as we better move forward, not backwards. In the meantime I have to stay with curl @7.59.0_0+ssl.

Just in case, I am attaching the full build log.
