Why are these being provided here?  Tekkotsu relies on libjpeg and libpng for image compression and decompression.  Mac OS X does not ship with these libraries pre-installed (or at least not in one of the locations search by Linux-style software), and so we provide installers as a convenience for our OS X users, and by extension, everyone else.
