On a clean Ubuntu system I have been running "build-webkit --gtk" then installing the dependencies that configure complained about. After they were all installed, my build failed with: /home/mrowe/Documents/Work/WebKit-git/OpenSource/WebCore/platform/image-decoders/jpeg/JPEGImageDecoder.cpp:46:21: error: jpeglib.h: No such file or directory This should be caught at configure-time.
