New description:
Since sage-5.10.beta2 there is a problem with the detection of dot2tex.
Even with dot2tex installed via
{{{
sage -f
http://sage.math.washington.edu/home/nthiery/dot2tex-2.8.7-2.spkg
}}}
it is not detected any longer:
{{{
sage: import dot2tex
...
ImportError: No module named pyparsing
}}}
This is crucial though since in combinatorics we heavily rely on being
able to draw pictures:
{{{
sage: B = CrystalOfTableaux(['A',2],shape=[1])
sage: view(B)
dot2tex not available. Install after running 'sage -sh'
}}}
dot2tex indeed needs pyparsing. And pyparsing used to ship with
matplotlib, but apparently the new version of matplotlib does not
include it anymore. So one need to install it somehow.
Comment by Paul-Olivier: It should be pyparsing 1.5?.x and not 2.x as
that's only in python 3.
