graphviz: There must be something wonky with their various scripts. There is

a configure switch (--without-cgraph) so tried that and ImageMagick will compile
without that Makefile sedit. Other graphviz dependent modules compile fine with this.

Even with this switch graphviz still twiddles about with things like; libcgraph.so.6.0.0T and
/usr/lib/libcgraph.so.6.0.0. It will still greate the .pc files related to cgraph. OK, whatever.
ImageMagick: Removing the if/then I put there yesterday.
