That's interesting. It looks like SBT is built with Scala 2.10 but
could be compiled with Scala 2.11:

http://stackoverflow.com/questions/23282469/does-sbt-build-against-scala-2-11

If we rebuild SBT with Scala 2.11 I guess we'll have compatibility
problems with the plugins. This would mean our sbt package would be
fine as a tool to build other packages, but it would be useless
(or quite limited) as a build tool for an end user downloading plugins
from the net.

So it looks like we'll need a scala-2.10 package as long as SBT
is unable to run with Scala 2.11.
