First, thanks very much for adding SVN read-only access. I admin a few repos and this is a really handy way to do updates on my colocated guild server. (I also use SVN to maintain most of my game addons, including Auctioneer, Omen, and Outfitter.)
I pulled the latest trunk, copied my conf.php from my old tarball-based install, and did the update from the web interface to update the database. I then clicked on the addons management page to install the vault addon. Went pretty smooth.
Most of my addons now show a purple square in the Installation column and complain that I overwrote them with an older version. (News and the freshly-installed Vault were the only ones showing anything else.)
From the main page, clicking on the Memberlist icon gets me the message/link "Click to Upgrade 2.0.0.0 to 1.9.9.1525". (Clicking on it appears to do nothing.)
Is this a DB issue? Do I need to tweak the DB to tell it the new version? Or should I be pulling addons from another place in the repo?
Here's what I see installed:
GuildBank v1.9.9.1431
Guild Info v1.9.9.1431
