 I've attached a Portfile patch. I added "universal_variant no", since I
 can't get neither GiNaC nor cln to build universally.

 The ftp-server requires an email as password. I just added
 "macports at example.net", but perhaps someone has a better solution? I don't
 know if there exists some sort of standard approach to this?
