In olsr-topology-view (OTV) the ImageMagick program is only required to display the finish graphic on the screen. If you are running OTV on MacOS you can avoid installing ImageMagick and use the Preview application to display the images instead.

Just replace the existing code around line 149 with the following:

if ($SHOW) {	
	if ($^O == "darwin") {	
		system "/usr/bin/open -a preview $TOPPATH/$NAME.$EXT &";
	} else {
		if ($ROOTWIN) {
			system "display -window root -backdrop $TOPPATH/$NAME.$EXT &";
		} elsif ($start) {
			system "display $FULLOPT -update 5 $TOPPATH/$NAME.$EXT &";
			$start = 0;
		}
	}
}

I have now made a few other changes:
• Added an option to use "dig" instead of gethostbyaddr() for address-to-name resolution. Gethostbyaddr() was missing a lot of host lookups.
• Suppressed links to 0.0.0.0/0
• Fixed a problem with the --linewidth option. They were sometimes so large they covered the entire page.
• Add a timestamp.
• Suppress duplicate edges (In a few cases I was seeing more than one path from a remote node to another.)
• Cosmetic changes

I'd be glad to share the code if anyone is interested.
