Apropos "md5-secured" distfiles:

If you use a proxy (e.g.squid) for ftp, it might use FTP-ASCII for
transfer, not BINARY, which might result in a inband conversation from
CRLF to LF in FTP for ASCII-files (.txt, .c, ... )

Some ports with distfile patches as textfiles or plain c-Sources 
(GhostScript, squid(?), ... ) complain about bad md5-sums.

Deleting this files and refetching without proxy 
(ftp_proxy="" portupgrade -rF foo/bar) is a manual workaround for this.

In some environments you don't have ftp without a (squid)proxy.

Any idea or better workaround?
