Support for Python 3

[sscirrus]

I am trying to play around with secure TLS websockets, which require a newer version of pyOpenSSL than the original 0.10-1, which requires Python 3+.

I know you've done incredible work to create newer software than the Yun 1.5.3 available on Arduino's website... does your repo support some newer pyOpenSSL than 0.10-1?

Unfortunately i've currently too little time to update the packages, so most of the them are currently outdated... First of all i have to update all packages to the latest version. Perhaps this adds support for the new pyOpenSSL version. Otherwise we have to find why the new version is not supported.

Building a new updated version can take a while...

I'm making progress. I managed to get a number of things installed.

What's happening now is a specific issue - this could help me get there. I have installed python 3.5, pip, and more.

$ opkg list-installed
# Not entire list:
libffi - 3.2.1-3
openssl-util - 1.0.2j-1
python3 - 3.5.0-3
python3-openssl - 3.5.0-3
python3-pip - 7.1.2-1

This page suggests that cffi is looking for libffi in the wrong place. Because libffi is installed by opkg, I find this plausible. But, when I do opkg files libffi, all I get is /usr/lib/libffi.so.6 and /usr/lib/libffi.so.6.0.4.

I wanted to create a symlink to help cffi find the libffi header files. But, all we have is source files.

So, I tried downloading the cffi tar file directly and extracting it. It wasn't clear how to install it (but if I could, I'd have the headers to point to!).

Please help me!
