What the documentation means by that is that our source code can be
built against OpenSSL versions as far back as 1.0.x.  Any particular
build, though, will work only with the OpenSSL major version it was
compiled with.  I speculate that you are trying to use a compiled
package that was made on some other version of your OS.  You didn't
say where you got the package from, so it's hard to offer more help
than that.
