Comment (by dstrubbe@…):

 Yes there are various other ports requring tk +x11 which would have the
 same problem:
 {{{
 math/R/Portfile:161:    require_active_variants
 path:lib/pkgconfig/tk.pc:tk x11
 science/magic/Portfile:35:require_active_variants tk x11
 science/magic-devel/Portfile:37:require_active_variants tk x11
 science/pymol/Portfile:56:require_active_variants tk "" quartz
 science/xcrysden/Portfile:36:require_active_variants tk x11
 x11/tix/Portfile:52:require_active_variants tk x11
 x11/xcircuit/Portfile:44:require_active_variants tk x11 quartz
 }}}
 Only the way pymol writes the requirement would work on 10.5.

 I think this patch should do the job.

 I am mystified how the variant descriptions are getting set in this port
 -- are there some automatic default descriptions that get applied?
