 Replying to [comment:17 vbraun]:

 > You should always merge (and never rebase) branches that are already
 published on trac, since somebody else might have used that already as a
 base for their own branch.

 Okay. Can't say I fully understand it yet, but I did that.

 > Here is the full buildbot log:
 
http://build.sagemath.org/sage/builders/%20%20fast%20UW%20mod%20%28Ubuntu%208.04%20x86_64%29%20incremental/builds/26
 It did compile libpng-1.2.35.p6, so thats your ticket.

 Indeed ! Don't understand it either. I just restarted a clean tree, used
 git (not sage's scripts) to fetch Pillow and #15561 in separate local
 branch, merged Pillow in 15561 and compiled (successfully).

 In the full buildbot log, the error points at pngconf.h line 328. That's
 the place where the error takes places while using the *unpatched*
 pngconf.h ; with the patched pngconf.h, the error should take place on
 line 334.

 Is it possible that buildbot's freetype compilation might pickup an
 unpatched (possibly system's) pngconf.h ? If so, how to prevent this from
 happening ?
