domino test should depend on core pyext, but it currently does not.
The error messages for test failures have the file paths based out of
the wrong directory (modules/module/test rather than the directory
that scons test was run from). This breaks emacs and other programs
which attempt to locate the files which caused the error. I typically
run the output through sed (or use a modified run-all-tests.py which
works from the root directory) to get around this, but that is a bit
annoying and it would be really nice if the all paths were relative to
the root dir.
