mac ports rsync error

Macports failed to install git-core because it failed to fetch rsync.

Error: Status 1 encountered during processing.

Can I manually download rsync-3.0.0.tar.gz and continue building?

I actually found there's no rsync-3.0.0.tar.gz on the above url of samba.org. Instead I downloaded rsync-3.0.2.tar.gz.

It also fails to to self update. I suspect it's because it's using the wrong version of rsync to sync with the rsync server of macports.org.

$ sudo port -d selfupdate

I think it's all due to my macports database is too old and thus the port file uses obsolete url to download and build rsync. But rsync is also used to update the mac ports database. Therefore I have to either manually update mac ports so that it can build the newer rsync or manually download and compile rsync to update the mac ports database.
