>Description:
The port for autotrace contains a patch (patch-input-magick.c) that patches autotrace to work with versions of ImageMagick that have four arguments to GetOnePixel.  This was apparently a temporary change in the API for ImageMagick that seems to have been reverted in the current ImageMagick port, which now has GetOnePixel returning a PixelPacket instead of having a fourth argument --- this is how it was in versions 6.4.4.  As far as I can tell, the GetOnePixel change lasted less than a month, probably because it broke too many other codes.

Anyhow, the patch now makes autotrace break when built against the current ImageMagick.

>How-To-Repeat:
Upgrade ImageMagick to the current version (6.4.7.5) and try to install autotrace.  It will abort compiling input-magick.c, complaining that the GetOnePixel call has too many arguments.
>Fix:
Remove the patch-input-magick.c patch file from the files directory of the port.
