---------------------+-----------------------------------
 Reporter:  egall@…  |      Owner:  macports-tickets@…
     Type:  defect   |     Status:  new
 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.1.3
 Keywords:           |       Port:  gtkmm pangomm cairomm
---------------------+-----------------------------------
 I currently have the following ports installed (that are relevant to this
 ticket):
 {{{
 Local-Admins-MacBook-Pro:~ root# port installed pangomm cairomm gtkmm
 pango cairo
 The following ports are currently installed:
   cairo @1.12.14_0+quartz+universal+x11 (active)
   cairomm @1.10.0_1+universal (active)
   gtkmm @2.24.2_1+universal (active)
   pango @1.34.1_1+quartz+universal+x11 (active)
   pangomm @2.28.4_1+universal (active)
 }}}
 Trying to upgrade, I run into these errors:
 {{{

 pangomm's and cairomm's `+quartz` and `+x11` variants don't actually
 conflict:
 {{{
 Local-Admins-MacBook-Pro:~ root# port variants pangomm cairomm gtkmm
 pangomm has the variants:
    quartz: Support for native Mac OS X graphics
    universal: Build for multiple architectures
 [+]x11: Enable X11 support
 cairomm has the variants:
    quartz: Support for native Mac OS X graphics
    universal: Build for multiple architectures
 [+]x11: Enable X11 support
 gtkmm has the variants:
    quartz: Support for native Mac OS X graphics
      * conflicts with x11
    universal: Build for multiple architectures
 [+]x11: Enable X11 support
      * conflicts with quartz
 }}}
 So it should technically be possible to install `pangomm` and `cairomm`
 with both `+x11` and `+quartz`. However, the way they use
 `active_variants` makes this impossible.
