Re: [julia-users] Cannot PyPlot / Matplotlib broken (warnings about font cache?)

[Steven G. Johnson]

For the font-cache, see
    https://github.com/matplotlib/matplotlib/issues/5836
...there is some ~/.cache/matplotlib directory that you can delete to get 
rid of this.

To tell PyPlot to use the Conda Python, you need to set the PYTHON 
environment variable and re-build PyCall:

    ENV["PYTHON"]=""
    Pkg.build("PyCall")
