[vtkusers] Bizarre Python Errors

[Mike Robertson]

Here's the result:

[localhost:local/vtk/VTK] root# python
Python 2.2 (#1, Apr 25 2002, 11:43:25)
[GCC 2.95.2 19991024 (release)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import vtk
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local/vtk/VTK/Wrapping/Python/vtk/__init__.py", line 8, in ?
    from filtering import *
  File "/usr/local/vtk/VTK/Wrapping/Python/vtk/filtering.py", line 7, in ?
    from libvtkFilteringPython import *
ImportError: Failure linking new module
>>> 

The reason I didn't compile with shared libraries is presumably specific to
mayavi. Here's the error it returns when vtk is compiled with sharing on:
[localhost:documents/temp/mayavi-1.0] root# python mayavi.py
Traceback (most recent call last):
  File "mayavi.py", line 4, in ?
    Main.main ()
  File "./Main.py", line 947, in main
    v = MayaVi (r)
  File "./Main.py", line 139, in __init__
    self.renwin = Misc.RenderWindow.RenderWindow (self.renwin_frame)
  File "Misc/RenderWindow.py", line 41, in __init__
    height=500)
  File "/usr/local/vtk/VTK/Wrapping/Python/vtkTkRenderWidget.py", line 65,
in __
init__
    vtkLoadPythonTkWidgets(master.tk)
  File "/usr/local/vtk/VTK/Wrapping/Python/vtkLoadPythonTkWidgets.py", line
59, 
in vtkLoadPythonTkWidgets
    interp.call('load', filename)
TclError: dyld: permission denied
[localhost:documents/temp/mayavi-1.0] root#

With sharing off, it returns no such Tcl errors; rather, the errors
correspond with those returned from the python shell.
