Recently, I want to run a script (PWgui) which requires Tcl (Itk). The manual suggests that I have to install iwidgets4 beforehand. I am using the university cluster and don't have any root privileges. My questions are:

  1. How to install iwidgets4 without root access?
  2. After the installation, how to set the environment so that Itk could be called whenever is needed? (The cluster uses .cshrc)
