Samba4 standalone mode trouble

[ccnp123]

Having some trouble setting up a real simple samba share on a fresh FreeBSD9.1. The only commands I've done are
portsnap fetch
portsnap extract
cd /usr/ports/net/samba4 && make install clean

Here's smb.conf:

[global] 
  workgroup = UNCAS
  server string = files
  log file = /var/log/%m.log
  max log size = 100
  security = user
  encrypt passwords = yes
  socket options = TCP_NODELAY
  preferred master = yes
  wins support = yes
  dns proxy = no

[www]
  comment = web files
  path = /www
  public = no
  writeable = yes
  directory mask = 0770
  create mask = 0770
  browseable = yes

If I try samba4 start it complains that I should start smbd, nmbd, and winbindd by hand if all I want is a simple share. So whatever, I do:

/usr/local/sbin/smbd start
/usr/local/sbin/nmbd start
/usr/local/sbin/winbindd start
In that order.

So to test, I try to smbclient -L to local host and this is what I get:

root@files:/usr/local/sbin # smbclient -L \\\\localhost -U parker
Enter parker's password: 
Failed to load upcase.dat, will use lame ASCII-only case sensitivity rules
Failed to load lowcase.dat, will use lame ASCII-only case sensitivity rules
protocol negotiation failed: NT_STATUS_IO_TIMEOUT
root@files:/usr/local/sbin #

What could be going on here? Trying the smbclient command on another machine gives the exact same timeout error.
