Hello,

here are some remarks that could help:
- src/3rdparty/javascriptcore is only related to QtScript (which you 
disabled in configure) so don't bother about it.
- 'jsc' is a standalone interpreter for JavaScriptcore and it shouldn't 
be compiled if you configure Qt since src/src.pro should explicitely 
"subdir" JavaScriptCore/JavaScriptCore.pro and WebCore/WebCore.pro in 
src/3rdparty/webkit/. So there might be something wrong around this.
- I don't know how well it works if you pick QtWebKit 2.1 and put it in 
Qt 4.7.
Alternatively, this is rather unofficial, but you can try to compile 
QtWebKit separately following instructions there: 
https://svn.webkit.org/wiki/BuildingQtOnLinux and run "make install" at 
the end. This should copy the QtWebKit library and headers to the Qt's 
install dir that was used to build QtWebKit.
