The usual way to set a dependency package is to add a 'select' statement for 
that package in Config.in. In this case ghostscript-fonts is not a hard 
dependency, because imagemagick is quite functional without it, and its size 
is non negligible. Maybe adding a comment to the help text in Config.in would 
suffice.

What do others think?
