 I'd like to use the xcscope elisp package to access cscope from emacs.
 This is in the contrib collection of cscope, but the port doesn't install
 it.

 Attached is a (very simple) patch to the cscope port to install xscope.

 It would probably be reasonable to make this a variant or even a separate
 port, but I'm not a big fan of variants and a separate port seems
 overkill.
