Them pointing to the correct place for you and not me may be because of the path kinds of issues that have been discussed so much already. I'm sure that source files are needed to compile code, though they don't always need to have copies(/links) made in the build directory (I have a huge number of build directories with zero source files for other projects), and autotools should usually be able to handle such things for you. But I do not come with intimate background on the specific build here.
