This should have been in commit
06c47695fc. The tests that use this
module did not fail because an import failure is assumed to be caused
by a missing dependency, not a genuine bug.
This prevents STDOUT lines from appearing out of order relative to
STDERR lines in the test log, which makes it much easier to understand
what's happening.

The version of Test::More available in CentOS/RHEL 6 doesn't include

drop support for CentOS/RHEL 6.
