On executing the following command - the following error occurs:

make[4]: *** [../priv/bin/x86_64-unknown-linux-gnu/ssl_esock] Error 1

in the file esock_openssl.c line 909 
I commented out the following function - and then it compiles correctly and I 
have not experianced any problems with SSL yet :)

   /* info callback */
    // if (debug)
    //  SSL_CTX_set_info_callback(ctx, info_callback);
