title: Missing tk.h and tcl.h files when building VRip
body: <p>I am trying to compile VRip in Ubuntu 10.04, using the site <a href="http://graphics.stanford.edu/software/vrip/guide/" rel="nofollow">http://graphics.stanford.edu/software/vrip/guide/</a> as a guide. It relies on installation of Tcl and Tk -- I have acquired the latest versions of these from the synaptic package manager.</p>
  
  <p>When I write "make depend", I get the error:</p>
  
  <blockquote>

  <p>It seems to be looking for header files and not finding them. But I'm not sure where to tell it to look. Could anyone with more experience help out? I've spent a good couple of hours trying to figure this out without any success... :S</p>
  
  <p>Thanks,
