       You need a working scalac, which is accessible for ant.
       This means, you should have `fjbg.jar', `scala.jar' and
       `tools.jar' on your classpath 

       check the ant-build-nsc  script! adjust to your paths if necessary.

    (*3) for Java, and pico, files are only recompiled if the source file is
    newer than the class file. This would work for scala, but mixin
    composition sometimes needs additional source files. These can
    be unavailable for some reason.
