Thomas Willingham a58d8d2c71 This error message had me confused for about twenty minutes. I couldn't
figure out what was wrong with my imagick install that would make it give
me an orange button if it was installed.  Of course, the problem was that
it wasn't installed, and the message was worded badly.  This is a bit less
confusing.
