   Thanks for the reply.   
      
   Short answer 'no', because the cpan site seemed to suggest building from   
   source (and scratching at the back of my mind from several years ago is   
   the idea it wasn't on cpan anyway).   
      
   But the cpan install tests fail, so it doesn't complete. I did   
   eventually find how to get round the library problem (link a couple of   
   stub .a files), but get the same test failure issues. Forcing install   
   fails at runtime, unsurprisingly.   
      
   I did notice that there's a cpan testing page that just looks ominously   
   red for failure mostly. Looks as though something changed in perl   
   several versions ago and zinc hasn't been fixed to match.   
      
   I also see the tkzinc domain is now something else entirely.   
      
   :-{ Good bit of code going to waste it would seem.   
      
   My program uses zinc to provide smooth scrolling of a full-screen image   
   across the screen - does anyone know of an alternative possibility please?
