QtWebKit source package includes generated files pre-generated (CONFIG=standalone_package). This means that from the QtWebKit source package one can build without a dependency on the generation tools like gperf, etc..
This property of the QtWebKit build is available for "WebKit1" builds but has not been carried over yet to WebKit2 builds.
