This is a piece of the current dev-python/imaging ebuilds: # Install headers required by media-gfx/sketch. install_headers() { insinto "$(python_get_includedir)" doins libImaging/Imaging.h doins libImaging/ImPlatform.h } python_execute_function install_headers However, the old "sketch" package was kinda renamed to "skencil", and even "skencil" doesn't run nowadays. By reading this comment I was confused if those headers were actually needed. Are they installed just for sketch, or they are useful for other packages? Thus, I suggest to either update the comment, or remove it.
The comment is now removed in -r2. I have left the headers since something else may need them.
