   The performance of the Unix random gatherer module (rndunix) is not
   very good and it does not keep the entropy pool over multiple
   invocations of GnuPG.  The suggested way to overcome this problem is
   to use the
  
                 Entropy Gathering Daemon (EGD)
  
   which provides a entropy source for the whole system.  It is written
   in Perl and available at the GnuPG FTP servers.  To enable EGD you
   should rerun configure with the option "--enable-static-rnd=egd".
   For more information consult the GnuPG webpages:
  
             http://www.gnupg.org/download.html#egd
