Yeah, I read about that, but still, I was thinking that as they ship 3.0.37,
it should also be easier to compile because OS has all that's necessary for
3.0.37. Newer Samba versions may have some dependencies (new libs or newer
version of libs), that might be harder to satisfy. I have never compiled
samba so far and all I know at the moment (from documentation) is that AD
support requires krb5 and openldap development libraries and files.
