Comment (by tscrim):

 I'd like this to also be a standard package.

 However just running `sage -i` on the spkg, I get the following:
 {{{

 sage: C = CrystalOfTableaux(['A',2], shape=[2,1])
 ERROR    Could not locate Graphviz binaries
 ERROR    Failed to create xdotdata. Is Graphviz installed?
 ERROR    Failed to parse the input data. Is it a valid dot file?
 Try to input xdot data directly. Example:
     dot -Txdot file.dot | dot2tex > file.tex

 If this does not work, check that you have an updated version of PyParsing
 and
 Graphviz. Users have reported problems with old versions. You can also run
 dot2tex in debug mode using the --debug option:
     dot2tex --debug file.dot
 A file dot2tex.log will be written to the current directory with detailed
 information useful for debugging.
 An exception has occurred, use %tb to see the full traceback.

 SystemExit: 1

 To exit: use 'exit', 'quit', or Ctrl-D.
 }}}
 which was working with the p1 spkg. I presume I shouldn't have to do
 anything else to get it to work, but what else should I try/do? (I don't
 think installing the (experimental) graphviz would work, nor does it seem
 like the right solution...)

 Best,[[BR]]
