10.0, no samba 4.1 package with pkgng

[Julien Cassette]

Freshports says samba 4.1 has a package ( 
http://www.freshports.org/net/samba41/ ) and there is a .tbz in 
http://ftp.freebsd.org/pub/FreeBSD/ports/packages/net/
However, it is not in pkg's repository:

# pkg search samba
cups-samba-6.0_7
samba-nsupdate-9.8.6_1
samba-virusfilter-0.1.3
samba36-3.6.23
samba36-libsmbclient-3.6.23_1
samba36-nmblookup-3.6.23
samba36-smbclient-3.6.23

Why isn't it available?
