Problem with git ports repository?

[Vince]

Hi All,
	I updated to the latest ports tree from the git repository and am not
getting the following errror when i try to make index (or in this case
portsdb -Uu) Is anyone else getting this? any ideas as to a fix?
I assume from the error its dns/bind9-dlz that erroring but cvsweb shows
the last commit for this to not actually change anything
(http://www.freebsd.org/cgi/cvsweb.cgi/ports/dns/bind9-dlz/Makefile.diff?r1=1.42;r2=1.43)

Before reporting this error, verify that you are running a supported
version of FreeBSD (see http://www.FreeBSD.org/ports/) and that you
have a complete and up-to-date ports collection.  (INDEX builds are
not supported with partial or out-of-date ports collections -- in
particular, if you are using cvsup, you must cvsup the "ports-all"
collection, and have no "refuse" files.)  If that is the case, then
report the failure to ports at FreeBSD.org together with relevant
details of your ports configuration (including FreeBSD version,
your architecture, your environment, and your /etc/make.conf
settings, especially compiler flags and WITH/WITHOUT settings).

Note: the latest pre-generated version of INDEX may be fetched
automatically with "make fetchindex".
