# Building with python integration seems to fail without 8G available
# RAM(!)  Since the memory check in check-reqs doesn't count swap, it
# may be unfair to fail the build entirely on the memory test alone.
# Therefore check-reqs_pkg_pretend is deliberately omitted so that we
# ewarn but not not eerror.
