Errors compiling clean checkout

I'm trying to build the latest plugin to try out a fix for a problem I reported in breakpoints. I've done a clean git checkout and pointed scala.properties at my scala 2.8.1 lib directory and my IDEA 10.5 RC application directory, but I'm getting some compile errors when dereferencing some IntelliJ classes…

I had been assuming the code was being built against the plugin SDK from 10.5. Was that a bad assumption? I'm building this on a Mac.
