Comment (by mojca@…):

 In the light of the change in r116066 (see #40333) and decision to not
 even try to properly support users who want to keep using the `+carbon`
 variant in wxPython I attached my proposal for changing the `py-
 robotframework-ride` port. After r116066 the port builds fine on the 10.6
 buildbot. If users want to play with Carbon, they are free to do so, but
 unsupported. And we can close this ticket and stop worrying about how to
 properly add `supported_archs` to the port.

 {{{
     variant wxpython30 conflicts wxpython28 description {Use wxPython 3.0
 with Cocoa (experimental)} {
         depends_lib-append  port:py${python.version}-wxpython-3.0
         notes-append "Warning: wxPython 3.0 is not fully compatible with
 robotframework-ride.\n"
     }

     variant wxpython28 conflicts wxpython28 description {Use wxPython 2.8
 with GTK} {
         depends_lib-append  port:py${python.version}-wxpython-2.8
     }

     if {![variant_isset wxpython30] && ![variant_isset wxpython28]} {
         default_variants    +wxpython28
     }
 }}}

 (PS: I think I forgot to increase the revision in the two attachments.
 Please don't forget about that if you commit the change.)
