Comment 1 Miro Hrončok 2019-10-13 00:09:29 UTC
I've hit it too early. Here is the actual report:

pythran 0.9.3 or 0.9.3post1 is not compatible yet with gast 0.3.x

The failure visible during the docs build:

+ make -C docs html
make: Entering directory '/builddir/build/BUILD/pythran-0.9.3post1/docs'
sphinx-build -b html -d _build/doctrees . _build/html
Running Sphinx v2.1.2

Configuration error:
There is a programmable error in your configuration file:

0.9.4 has been released yesterday, it should fix this issue.
