I'm surprised it matched - the test is:

                # Check version is supported.
                case "$ssl_library_ver" in
                        0090[[0-7]]*|009080[[0-5]]*)
                                AC_MSG_ERROR([OpenSSL >= 0.9.8f required])
                                ;;
                        *) ;;
                esac

Are you sure your library matches your header? You can see what configure
found by looking at the 'result' line in config.log that follows
'checking OpenSSL library version'.

I've altered the error message to include the actual version found.
