Hi Javier,

try to switch python to python2 during the build, then you can switch 
back to python3:

$ sudo ln -sf /usr/bin/python2 /usr/bin/python
[ do the build ]
$ sudo ln -sf /usr/bin/python3 /usr/bin/python

It's ugly, I know.
Also you can try to use virtualenv2, it's explained in the wiki [1].
