Starting ipython notebook from the command line, you get the following output: marbre@flyingdragon ~ $ ipython3.4 notebook [I 22:58:14.313 NotebookApp] Serving local MathJax from /usr/lib64/python3.4/site-packages/IPython/html/static/mathjax/MathJax.js at /static/mathjax/MathJax.js [W 22:58:14.333 NotebookApp] Terminals not available (error was No module named 'ptyprocess') After installing dev-python/ptyprocess from the science overlay, to which I have recently added ptyprocess, this message disappears. Maybe, ptyprocess should be added to the tree and added as dependency to ipython when the notebook useflag is chosen. Reproducible: Always
A grep for ptyprocess in ipython yields nothing. Are you sure that you are using ipython-3.1.0?
ptyprocess is a dependency of terminado. So it is a transitive dependency for ipython-notebook.
