# Don't even think about this ... for some platforms the default
# test_via_script from MakeMaker pre-pends the perl invocation lines
# for the "make test" rules with "PERL_DL_NONLAZY=1" which makes the
# test fail ... at least on Ubuntu 14.10
# I found the basics of this hack on the web ...
# http://www.perlmonks.org/bare/?node_id=443998
# and the explanation in the An ExtUtils::MakeMaker Example section
