Comment(by dweber@…):

 Replying to [comment:4 tgamblin@…]:
 > I think this is because you did not put -carbon in your build line.  I
 can build +python +x11 -carbon fine on my system.  I do not believe that
 you can't build VTK with more than one of carbon, cocoa, or x11 -- is
 there a way to express that in the Portfile so it warns you about the
 variants you selected being incompatible?

 See http://guide.macports.org/#reference.variants, ie:
 variant name [requires variant] [conflicts variant] [description
 description]


 > Also, do you think the default variants should be changed?  I mentioned
 above that the current port of vtk5 builds, by default, with:
 >     +python +x11 +tcltk
 >
 > In the portfile I submitted (which has apparently confused you) the
 defaults are:
 >     +carbon +python

 > The question is whether the current set is the right set of defaults for
 MacPorts, since other Ports (like Qt4) default to prefer native guis like
 cocoa/carbon instead of X.  I think mac users trying vtk for the first
 time might expect that it use a native GUI.  The problem with that is that
 I think most VTK users are going to expect tcl/tk support (since that was
 the first scripting language VTK supported), but I can't seem to get
 carbon and tk to build together properly.  I *did* successfully build with
 cocoa, python, and tcl/tk, but VTK 5.2 won't embed properly in Qt unless
 you build with Carbon (b/c there are some unimplemented methods in the
 cocoa render window).  Sigh.

 the X libraries that I could not figure out.

 + x11

 Whatever you decide, do try configure to configure the variants using the
 'requires' and 'conflicts' phrases to get all these configuration
 dependencies resolved.

 Best, Darren
