Makefile possibly broken: graphics/ImageMagick

[Jos Chrispijn]

Dear ports maintainer,

Would like to report this issue. I ran into it when I did a port upgrade.

"/usr/ports/Mk/Uses/ghostscript.mk", line 68: Malformed conditional ()
"/usr/ports/Mk/Uses/ghostscript.mk", line 72: Malformed conditional ()

Can you advise how to process further?
