LibreSSL is rather close to OpenSSL in terms of API compatibility as far as I recall, OpenBSD using it. Note that we have two buildfarm members that I guess are doing so (adding Mikael in CC to confirm here): morepork and plover. The configure option --with-openssl would be the one to use, but you'd better be sure that CFLAGS is pointing at the path(s) of the headers of LibreSSL and that LDFLAGS points to the libraries of LibreSSL if you have an environment mixing both. Then at run-time, you could force LD_LIBRARY_PATH to load the right thing. There may be trickier things like building with OpenLDAP for example, as Postgres built with --with-ldap could link to a version of OpenLDAP linking to OpenSSL, but you'd want LibreSSL for a full consistency, so be careful.. The same could happen with Python, but without knowing what kind of environment you are using it will be hard to reach a clear conclusion without at least more details. -- Michael
