[vtkusers] can not find some function of R when use R integrated in vtk

[Wes Turner]

Wen Li,

Thanks for sending this back.  This is undoubtedly something that we will
have to understand better as we move forward.  I would expect that it is
mainly a matter of cleaning up the environment and setting paths/shared
libraries correctly.  Is your machine a windows box, or Linux, or Mac, or
...?  The easiest trick we have found so far, is simply to include the
correct R libraries in the directory with the executable.  That is the first
place that should be searched.  I will post if we get a better solution.

- Wes
