The Ghostscript tarball contains a set of 35 fonts.  The 
Ghostscript build embeds those fonts in libgs.so.  That’s 
configurable.

Why does the port ghostscript-fonts exist?  Why does the 
ghostscript port depend on it, if it doesn’t use it?  We could 
drop ghostscript-fonts and let Ghostscript have its own fonts 
installed in the file system, no?
