I'm unable so far to get xpdf-tools to build statically on the mac. These are the changes to get it to build on the Mac in an attempt to make static xpdf-tools binaries. Running otool minus L on the binaries however shows that they're linking to dylib dlls, albeit our ones for freetype, libpng and zlib.
