Bug#918827: atheist: FTBFS with Sphinx 1.8: No module named pngmath

[Dmitry Shachnev]

Source: atheist
Version: 0.20110402-2.1
Severity: important
User: python-modules-t...@lists.alioth.debian.org
Usertags: sphinx1.8

Dear Maintainer,

atheist fails to build with Sphinx 1.8, currently available in
experimental:

  /usr/bin/make -C doc html
  make[2]: Entering directory '/<>/doc'
  python /usr/bin/sphinx-build -b html -d _build/doctrees   . _build/html
  Running Sphinx v1.8.3

  Extension error:
  Could not import extension sphinx.ext.pngmath (exception: No module named 
pngmath)
  make[2]: *** [Makefile:43: html] Error 2

The pngmath extension was deprecated in Sphinx 1.4 and has been removed [1]
in Sphinx 1.8. The recommended alternative is sphinx.ext.imgmath [2] which
also has SVG support in addition to PNG.

To me it looks like this extension is unused anyway: there are no “.. math::”
directives or “:math:” roles, and the binary package does not have any
generated PNG images. So this extension can be simply removed from extensions
in conf.py.
