As previously discussed during the recent staging cycle, VTK is failing
to build, which in turn prevents FreeCAD from building:

------
Here's what I wrote during the staging cycle:
------
For example, the vtk package is broken due to incompatibility with new
Freetype, which breaks FreeCAD. On #guix, Marius said "I looked into VTK
before the holidays; the Freetype issue is fixed in version 9, but that
has other problems, such as making it impossible to unbundle the dozens
of libraries that we are currently unbundling [...] it is possible to
backport the VTK commits that fix Freetype compatibility, but it will be
a lot of work and a huge patch (it was a major cleanup IIRC)." I'm
CC-ing Ekaitz Zarraga, who has been working on FreeCAD. I'm not sure
what we can do about this problem in the short term. Marius, can you
give more info about the bundling problem?
------
Ultimately, it seems to be a compatibility issue, combined with
difficulty of "updating our way out of it". Maybe we should re-instate
the graft? I know it's icky to think that the graft was masking some
problem, but is it worse than not having the affected packages at all?
Were things actually not working while the graft was in place? What do
you think?
