Installing Apache2 fails due to unfetchable files

Hi, I'm trying to install Apache2, and it is failing with the following error:

---> Attempting to fetch db-4.4.20.tar.gz from http://svn.macports.org/repository/macports/downloads/db44 Error: Target org.macports.fetch returned: fetch failed

Browsing to this location reveals that there is indeed nothing there. I have run port selfupdate, and port sync (for good luck rather than actual use), and believe I am up to date with everything. Any suggestions please? Thanks, S
