Running 10.7.4, I ran the following:
mkdir -p /opt/mports
cd /opt/mports
svn checkout https://svn.macports.org/repository/macports/trunk
cd trunk/base
./configure --enable-readline
make
sudo make install
make distclean
Then I ran nano /opt/local/etc/macports/sources.conf
, commented out rsync://rsync.macports.org/release/tarballs/ports.tar
and added in file://opt/mports/trunk/dports [default]
After running sudo port -d sync
I received

Updating via rsync works fine, but not when using local sources. Also, I was given the option to accept the certificate when checking out at the beginning, and I chose to accept it permanently.
