Doing a world update pulled in dev-python/cvxopt-1.1.9, which failed as follows: --- [...] sphinx-build -b html -d build/doctrees source build/html Running Sphinx v1.3.1 Extension error: Could not import extension sphinx.ext.imgmath (exception: No module named 'sphinx.ext.imgmath') make: *** [Makefile:30: html] Error 1 make: Leaving directory '/var/tmp/portage/dev-python/cvxopt-1.1.9/work/cvxopt-1.1.9/doc' * ERROR: dev-python/cvxopt-1.1.9::gentoo failed (compile phase): * emake failed [...] --- Perhaps some missing dependency?
Works with sphinx 1.4.4, presumably will work with 1.5.x. The dependency to sphinx should be raised to a minimal version I guess.
