bin/element-info accesses it's library via a symlink: bin/diskimage_builder -> diskimage_builder This causes the relative path in elements.py to be incorrect. element-info silently fails in this situation, because it allows missing 'element-deps' files, so that these files may be optional. This change causes element-info to fail explicitly if $ELEMENTS_DIR is not set, as it now is when called by diskimage-create, and adds tests reflecting this behavior.
