Samba-4 fresh compile, /usr/local/samba/var/lib missing?

[Scott Lovenberg]

Can anyone else confirm what I'm seeing?  I ran through a full compile, 
but upon starting smbd, I get:
<quote>
error creating directory /usr/local/samba/var/lib/winbindd_privileged: 
No such file or directory
task_server_terminate: [Cannot create winbindd privileged pipe directory]
</quote>

Turns out, I don't have a lib directory! 
If I make the directory, the error goes away.  Anyone else seeing this?

Slackware-12.0 proper, in a VMWare guest for testing.
