[Neuroimaging] Problem with from dipy.viz.fvtk

Hi Ariel,

Thank you very much for the reply!
So, this is what happens if you import vtk in python:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-b7e11aadda62> in <module>()
----> 1 import vtk

/usr/lib/python2.7/site-packages/vtk/__init__.py in <module>()
     88 from .vtkParallelCore import *
     89 from .vtkFiltersAMR import *
---> 90 from .vtkIOAMR import *
     91 from .vtkRenderingVolumeOpenGL2 import *
     92 from .vtkFiltersFlowPaths import *

/usr/lib/python2.7/site-packages/vtk/vtkIOAMR.py in <module>()
      7     # during build and testing, the modules will be elsewhere,
      8     # e.g. in lib directory or Release/Debug config directories
----> 9     from vtkIOAMRPython import *

ImportError: No module named vtkIOAMRPython

I found this link, which I think will work:
http://ghoshbishakh.github.io/blog/blogpost/2016/03/05/buid-vtk.html

Though, after "cmake ." I get another error:

CMake Error at CMake/vtkCompilerExtras.cmake:47 (if):
  if given arguments:

    "cc: error: ARGS: No such file or directory

  Unknown arguments specified
Call Stack (most recent call first):
  CMakeLists.txt:286 (include)

-- Configuring incomplete, errors occurred!

Which I think is due to gcc's compilation.. I am trying to fix this.. If I
manage to, I will report it!

But of course, if you had to suggest something different, it would be
welcomed! :)

Thanks again,
Vassia
