Are those errors expected? Any other suggestion? As I mentioned earlier, the error message from gs is expected and can be safely ignored for perfbook.pdf generation. Please restore Makefile by "git checkout -- Makefile". Glad to know you can now build .pdf on your own. And if you will ever do the first-time build again, you can do parallel make by saying "make -j4" (4 is for a quad-core machine). You can try it by "make neatfreak; make -j4" if you'd like to.
