I didnt see earlier mails in the thread, but I assume the problem is
that lftp gets a corrupted distfile when fetching through a squid
proxy.  This is because in the default configuration squid fetches all
plain text files in ftp ascii mode, which does CR/LF translation and
botches up the checksum.

IMO this is a bug in the squid configuration.
