[Neuroimaging] Problem with from dipy.viz.fvtk

[Samuel St-Jean]

I am currently on arch (manjaro uses the same repo for the most part), 
and I just realized it is indeed plain broken, I'll flag a bug report 
for that. The repos also have vtk6, which get installed to a non 
standard path, and is also broken unfortunately.


If you don't need it right now, they usually fix and rebuild stuff 
pretty fast, so might be worth to wait a few days before compiling 
everything in cmake if it's not urgent.
