Interesting. I recall a while back that backpress had to be added manually, but I thought that was resolved. backpress has it’s own trac:

http://backpress.automattic.com/browser/tags

Maybe you can grab it from there and create a backpress directory in bb-includes and put the files there? Maybe an svn:external failed? It’s a weird error that I have not seen before, at least not since the alpha versions of 1.0.
