48 # - If a package has an unspecified optional dependency and that
49 # dependency is present when the package is built, it is used,
50 # otherwise it isn't (but compilation happily proceeds) so the end
51 # result will differ if the order is swapped due to parallel
53 # - Also changing the building order can be a problem if two packages
54 # manipulate the same file in the target directory.
56 # Taking into account the above considerations, if you still want to execute
57 # this top-level Makefile in parallel comment the ".NOTPARALLEL" line and
58 # build using the following command:
