During my upgrade to ImageMagick-18.104.22.168, the following issues occurred using Portupgrade on a FreeBSD 8 system:
"gtkscalebutton.c:544: Warning: Gtk: invalid annotation option: int"
I needed to "portupgrade gobject-introspection" and restart portupgrade for Imagemagick
GdkPixbuf-WARNING **: Bug! gdk-pixbuf loader 'png12' didn't set an error on failure.
I needed to "portupgrade gdk-pixbuf" and restart portupgrade for Imagemagick
