 OpenSSL 1.0.0a allows for extensions for md2, kerberos, and others as well
 as moves to using system (MacPorts) provided zlib.  I'm attaching a patch
 to the current (1.0.0a, epoch 1, revision 0) Portfile to allow these
 changes.  The default install isn't changed, and in my testing openssl
 works just before with or without the variants (the variants are plugin
 extensions and headers, and do not impact the application).
