Hi, SAGE_BINARY_BUILD was introduced as a compromise when it was decided that libjpeg and libtiff were to be introduced first as optional packages, since PIL is a standard package. Without SAGE_BINARY_BUILD set, binary distributions have PIL link with libjpeg and libtiff as shared libraries, which may not exist in client machines. (c.f. http://groups.google.com/group/sage-devel/msg/6ea0a0e0a0a2a71a and http://trac.sagemath.org/sage_trac/ticket/7273)
The libjpeg and libtiff packages are at http://trac.sagemath.org/sage_trac/ticket/7344 and http://trac.sagemath.org/sage_trac/ticket/7345. However, they have some issues that I cannot attend to right now due to time constraints.
