[vtkusers] VTK Python Wrappers on Red Hat

[Darren Weber]

Hi Brian,

I had similar problems in porting vtk 5.4.0 in macports.  My solutions might
work for you on linux:
https://trac.macports.org/browser/trunk/dports/graphics/vtk-devel/Portfile

See variant py25 and py26, where the build bin path has to be replaced with
the install lib path for all the python shared libs (.dylib on OSX, .so on
linux).  Do you also have 'install_name_tool' on linux?

Best, Darren
