make fails on a sed call on Mac OS X

Hi all, I just tried to build the guide and get: MININT-NSR6ILC:guide karianna$ make pandoc src/changePlanning.md --css guidestyle.css --strip-comments --standalone --ascii --title-prefix "The OpenJDK Developers' Guide" | iconv -f UTF-8 -t ISO-8859-1 > build/changePlanning.html sed -i "" "/^ <meta charset=/d" build/changePlanning.html sed: can't read /^ <meta charset=/d: No such file or directory make: *** [build/changePlanning.html] Error 2 Anyone else experience this before I start digging in? Cheers, Martijn
