[webkit-help] Compile Web-kit error because of libwebkit-1.0.so

[thangdd]

Hi, everybody!
I am a newbee in webkit. I 've been downloaded source code of 
WebKit-r54277. And compiling it:

$ ./autogen.sh --with-target=directfb --prefix=/usr/
$ make
...
When compiler comes here, it gets errors:

I have built libxt and xlib, gtk-directfb, gtk-x11 at all.
I search these errors in google, but there is any right answer.
Thanks for your helps.

Best regards,
