-------------------------------------------------+-------------------------
 Gentoo apparently has special snowflake OpenSSL > 1.0 that is missing ECC
 support unless explicitly enabled.  Since we only check the OpenSSL
 version and not if ECC support is present, the build fails at `make` time
 rather than `configure` time.

 We should fix this so it fails earlier rather than later.
