Comment (by mojca@…):

 In r116076 I changed the port in such a way that it depends on wxWidgets
 no matter what. If anyone really needs the software without any GUI, we
 can look at this again. It's probably still worth submitting a bug report
 upstream if anyone cares enough, but in it's current form it doesn't
 affect the port in MacPorts any longer.

 Just to answer the last questions:

 Replying to [comment:6 egall@…]:
 > - Why is the wxWidgets PortGroup used outside of the `+wxWidgets`
 variant?

 Because it doesn't matter. The PortGroup itself doesn't do any
 modifications and doesn't change the port in any way. One needs to
 explicitly use
 {{{
 wxWidgets.use wxWidgets-2.8
 }}}
 to restrict the set of platforms or throw an error when incompatible
 platform is used for example. And dependencies need to be added
 explicitly.

 > - Why is `wxWidgets.use` set to `wxPython-3.0` outside of the
 `+wxPython` variant?

 Same as above: because it doesn't matter until one actually uses
 {{{
 depends_lib-append port:${wxWidgets.port}
 }}}

 but I changed that last part in r116076 where two different versions are
 supported.
