    Yeap ... me too.
    I was building it on Debian Wheezy and got this:
    Qt Code: 
    1. ...
    2. g++: error: unrecognized command line option ‘-fuse-ld=gold’
    3. g++: error: unrecognized command line option ‘-fuse-ld=gold’
    4. g++: error: unrecognized command line option ‘-fuse-ld=gold’
    5. make[2]: *** [../../../../../../lib/libQtWebKit.so.4.9.3] Error 1
    6. make[2]: Leaving directory `/home/gt/Documentos/qt-everywhere-opensource-src-4.8.3/src/3rdparty/webkit/Source/WebKit/qt'
    7. make[1]: *** [sub-WebKit-qt-QtWebKit-pro-make_default-ordered] Error 2
    8. make[1]: Leaving directory `/home/gt/Documentos/qt-everywhere-opensource-src-4.8.3/src/3rdparty/webkit/Source'
    9. make: *** [sub-webkit-make_default-ordered] Error 2
    To copy to clipboard, switch view to plain text mode 

    What am i doing wrong?
