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.

'''md5sum:''' `d096c3eec2a2f3bdd74a3e31b5c6872d dot2tex-2.8.7.p2.spkg`
=== dot2tex-2.8.7.p2 (Leif Leonhardy, May 20th 2013) ===
* #14594: Make dot2tex work with matplotlib 1.2.x (as well as older
versions)
Update `patches/use-matplotlib-pyparsing.patch` to either import
`matplotlib.pyparsing` or `matplotlib.pyparsing_py2`.
* Clean up `spkg-install` and `spkg-check`.
Apply patches from within `src/` (still with `-p1`).
Let `spkg-check` exit with an error if *any* of the tests failed, not
just
the last one.
* Update / fix `SPKG.txt`, also adding some entries in standard format
for
previous (now tagged) spkg versions.
* Add patch to `tests/test_comparedotparsing.py` skipping comparisons to
non-existent (i.e., missing) reference files.
* Add patch to `tests/test_buildexamples.py` fixing the build order,
since
otherwise `graphofgraphs.tex`, which includes the output of other
examples,
fails to build.

Comment:
Just for the record, the
[http://boxen.math.washington.edu/home/leif/Sage/spkgs/dot2tex-2.8.7.p1.spkg
.p1 spkg] is a remake of Nicolas' `dot2tex-2.8.7-2.spkg`, with all traces
of upstream files removed from the Mercurial history (and `src/` now in
`.hgignore`), and some tags added.
For the
[http://boxen.math.washington.edu/home/leif/Sage/spkgs/dot2tex-2.8.7.p2.spkg
new .p2 spkg] with my fixes, based on the above-mentioned `.p1`, see the
ticket's description; [attachment:dot2tex-2.8.7.p1-p2.diff diff for easier
reviewing] also attached. Please build, test, and report! ;-)
(Supposed to work with older Sage / matplotlib versions as well.)
