The instructions for building from source are broken, it seems.
1) The project/build.properties files points to 0.7.5RC0, which is no
longer available from the standard repositories. Changing this to 0.7.5
lets us proceed.
2) recursivity-commons needs the same fix, but then doesn't compile, with
object scalap is not a member of package tools
[error] import scala.tools.scalap.scalax.rules.scalasig._
[error] one error found
As such, I've failed trying to build bowler from source even under 2.9, let
alone trying 2.10.
