Please provide matplotlib

[alansaul]

Hello, a few months ago issue #217 requested numpy and matplotlib to be installed, I have noticed that indeed numpy and scipy are now installed and I can import them with no issue, but I don't seem to be able to import matplotlib. My project is in a virtualenv and has use system packages enabled.

Let me know if there is anything I can do to help.

Should be there now. At least I apt-get installed it. It still appears to have issues building on the system for some reason from pip though.

I saw the same problem building matplotlib before realizing from this issue that it's now a system package. From the logs there, I think the failure came from libfreetype2 not having headers (maybe also libpng). So if you apt-get the dev versions of those packages, it may work in pip even without ''--use-system-packages''

I am more in favor of just using it as a system package than trying to make it able for others to build for now. C packages are the most prone to breakage due to needing older/newer versions of other -dev packages so using the system version is simpler.

Which version of matplotlib is installed? My project requires v1.1.1, so it's attempting to pip install it even though i'm using system site packages. The build fails due to missing headers. Would you guys be willing to:

apt-get install libfreetype6-dev libpng-dev

? WIth those two pkgs installed, the build would succeed.
