 So you have a rogue copy of the libtool dynamic loader in /usr/local that
 is causing problems. This type of problem is why we don't support people
 having things installed in /usr/local while using MacPorts. Please move
 /usr/local aside (e.g. rename it to /usr/local-off), clean GraphicsMagick,
 and try again.
