I noted yesterday that Xcode wouldn’t recognize my Subversion install. I was getting an error that said http://localhost:8800 was unreachable. However, I could enter that into safari without any problems.

I was reading through the comments on the MacZealots Subversion tutorial and someone mentioned that switching apache from port 8800 to port 80 (and thus conflicting with the default Tiger install of Apache 1.3) fixed this. I tried it and it does indeed work!

If you want to try this, re-edit your httpd.conf file and replace your “Listen 8800″ line with “Listen 80″. Stop your Apache2 server, and then restart it. Also make sure that your Personal Web Sharing is turned off. The default Apache installation that came with Tiger will try to use port 80, so if you have it turned on, your Apache2 installation with Subversion will not start.
