[16:21:20] <wiredfool1> rjt: dev versions are required for the headers, see the install docs @ http://pillow.readthedocs.org/en/3.1.x/installation.html#building-on-linux for a list of packages for 2 LTS versions of ubuntu
[22:07:25] <rjt> wiredfool1: i am running LinuxMint and for some reason, many or most of the dev packages are not found by apt cache. Probably time to wipe harddrive and reinstall.
