samba - Jan 2012 - samba-tool

I have been trying yo follow along with the tutorial
http://wiki.samba.org/index.php/Samba4_joining_a_domain and it references
samba-tool. Is there a substitution or change of name for samba-tool in samba4?

I installed samba4 @4.0.0tp5_0 using the MacPorts and only the following
commands seem to be available in /opt/local/bin:

     1 ad2oLschema4*
      2 cifsdd4*
      3 gentest4*
      4 getntacl4*
      5 ldbadd4*
      6 ldbdel4*
      7 ldbedit4*
      8 ldbmodify4*
      9 ldbrename4*
     10 ldbsearch4*
     11 locktest4*
     12 masktest4*
     13 ndrdump4*
     14 net4*
     15 nmblookup4*
     16 ntlm_auth4*
     17 oLschema2ldif4*
     18 regdiff4*
     19 regpatch4*
     20 regshell4*
     21 regtree4*
     22 samba3dump4*
     23 setnttoken4*
     24 smbclient4*
     25 smbscript4*
     26 smbstatus4*
     27 smbtorture4*
     28 tdbbackup4*
     29 tdbdump4*
     30 tdbtool4*
     31 tdbtorture4*
     32 testparm4*
     33 winreg4*

In /opt/local/sbin there is a samba4 command.

Thanks,
Mikel
