[IMP-dev] Minor issues encountered

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.
