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

[thangdd]

Hi, everybody!
I am new in webkit-dev. 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.
