pip install fails when pointed to downloads.leap.se
reported in ubuntu trusty, when executing bootstrap_develop.sh, which I recently modified to fetch pixelated modules from a folder in downloads.leap.se. this seems to be related to an issue with the python version and sni, see: https://github.com/pypa/pip/issues/1511
a workaround for the moment might be to add a try/except for the import of these modules (pixelated).
