## Some contents of morphologies (description, build-depends, chunks)
## should not change the cache keys of those morphs because they are
## either already considered (build-depends and chunks) or do not affect
## building (description). This test checks that changes to these parts
## of a morphology do not force rebuilds.

# FIXME: This seems to break because the new "morph edit" makes correct
# changes to build-dependencies, which breaks the old "morph build".
# Disable test now, re-enable it after "morph build" is fixed. --liw
