Pillow tarball

[Trevor Karn]

Hi all,

When trying to build on Ubuntu, I got an SSL certificate error (see below). This only seemed to be an issue with pillow, everything else seems to be working fine. I was able to manually download the pillow tarball and proceed with the build, so I don't need any help per se, but I am just wondering why SSL certificates would cause this one step to fail and not all third party packages? Any thoughts?

Best,

Trevor
