[Paraview] help

[ysh]

I have a problem about paraview when I uses OpenFoam.
   I have installed paraview as following:
   tar -xf paraview.1.8.0.tar
   when I enter the directory 
     $HOME/OpenFOAM/linux/paraview1.8.0/bin and run paraview,an error printouts as following:
-----------------------------------------------
    ParaView error:initialize Tcl failed
    TK_Init error:invalid command name "Tcl_findLibrary"
-----------------------------------------------
    How can I correct this error?
    Thanx.

   S.H.Yang
