no pop mail with git head

[Jack <ostroffjh users sourceforge net>]

I just did a git pull --rebase, autogen.sh, and then configure with some 
options different from the default autogen.  (I know I could give those 
options to autogen, but I already have the ./configure command in a file.)

Trying to fetch mail gets me "POP3 mailbox mailboxname: cannot connect 
localhost: error: unknown command or bad syntax" for every pop3 
mailbox.  It's localhost because I use popfile as a spam filter, but 
it's been working fine for years.  In the popfile log, I see:

2017/4/15 17:40:30 2851: pop3: 311: +OK POP3 POPFile (v1.1.3) server 
ready[0d][0a]
2017/4/15 17:40:30 2851: pop3: 198: Regexps: ^USER XXXXXX

syntax[0d][0a]

2017/4/15 17:40:30 2851: pop3: 682: POP3 proxy done

for each pop3 server.  I saw no errors during configure or make. I'll 
give a try going directly to the server without popfile.   I did try 
with both TLS required and with POP3S, although with the latter, I don't 
see an entry in the popfile log, and with no security I see --CAPA-- as 
the command followed by "-ERR No secure server specified" even though I 
have :ssl at the end of the user name, which is how it's always worked.

Also - I tried 'balsa -d' but it says Unknown option -d.  Was this 
intentionally removed?

Thanks for any suggestions.
