Hey everyone,
    Since at least 5.10.beta2, the dot2tex package installs, but is no
longer recognized by sage:

sage: B = CrystalOfTableaux(['A',2],shape=[1])
sage: view(B)
dot2tex not available.  Install after running 'sage -sh'

See ticket.

Apparently only the (already present patch in the) dot2tex optional spkg has to be changed, into trying to import matplotlib.pyparsing_py2 if importing matplotlib.pyparsing raises an ImportError. (Not tested.)

I've set the ticket http://trac.sagemath.org/sage_trac/ticket/14594 as a
blocker since all of the crystal graphs can no longer be created. I've
tried a few things, but I'm out of my depth here. Any help would be
appreciated.

Thanks,
Travis
