Just ran the tests and it failed on an old gadfly
version here.
As not all people want to use gadfly the test should
not fail but
print a warning and then continue.

I've done a crude patch (attached) and noted that
there are three places where round-up checks for gadfly.
Only one place should be enough and the tests should
reuse that
information.
