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

[Wes Turner]

I believe that you can (I have multiple R installations on my windows box
and it works).  Setting it up is slightly different than on Linux (I only
have one R installed on Linux).  I believe the first library encountered in
LD_LIBRARY_PATH is the one that gets used preferentially, so if you do
something like export
"LD_LIBRARY_PATH=preferred_R_installation:$LD_LIBRARY_PATH" it *should*
work.
