I've also been struggling with Samba for 506 and had problems with 3.0.9.

I suspect you might be better off installing 3.0.1 from
ftp://ftp.aplawrence.com/pub/zini/samba_506.tar.bz2

uncompress it with bzip2,
untar it into /usr/local,
create a /usr/local/samba/lib/smb.conf
run /usr/local/samba/sbin/nmbd
run /usr/local/samba/sbin/smbd

You should then be able to access the shares from a Windows PC.

My smb.conf came from a (now uninstalled) samba 2.2.6 and is not
thoroughly tested.

Caveat Emptor. YMMV. Batteries not included.
