How to get a copy of an old, removed port?

I've been gone for a while, and I noticed that the 'shorewall' port was removed a few months back for lack of a maintainer. I don't have a copy of it, and while I could put one together myself, I'd rather save the work. Is there an easy way to look at old versions of the repos? I tried doing an SVN checkout according to the wiki instructions <http://crux.nu/Main/SvnHowTo>, hoping I could look through the old revisions until I found it, but I keep getting 405 errors from the server. Also, if anyone has a copy of the 'shorewall' port from the last year, that would solve this, too. -Ryan
