   * --with-libevent=/path/to/libevent
        Can be set to either the system install or the build directory.
        --with-libevent=no gives a builtin alternative implementation.
+       libevent is useful when having many (thousands) of outgoing ports.
+       This improves randomization and spoof resistance. For the default 
+       of 16 ports the builtin alternative works well.
   * --without-pthreads 
        This disables pthreads, and uses Solaris thr library or no threading. 
        Without this option the pthreads library is detected automatically.
