Could be a classpath issue.  Could also be this just doesn't work for
libraries loaded from source a compile on-the-fly,  That has
probably not been tested as much as one would like.

Notice how the class lib.test is complaining that lib.test isn't found ...
Probably some ClassLoader not being set up right.
Possible a missing call to Compilation.usedClass.

If you can make a simple self-contained test-case I'll look into it.
