It wasn't just scala-library and scala-compiler. It was scala-continuations-library, scala-continuations-plugin, scala-actors-migration, scala-compiler, scala-library, scala-parser-combinators, scaka-reflect, scala-swing, and scala-xml. I have already manually installed them and it works fine, but I would prefer not to have to do this on every computer my friends own, just because I want them to play mods with me, and they don't know how to install them.
