/home/attilio/dfb_2.7.0-1/usr/lib
First your missing a -L/home/attilio/dfb_2.7.0-1/usr/lib
Not sure why its actually in the pc file
gtk+-2.0.pc
Libs: -L${libdir} -lgtk-${target}-2.0 for example its all of them.
Probably if your trying to move precompiled libraries around the pc
files in pkgconfig are not right you need to change the prefix by hand
in each pc file.

This error means no Directfb backend was found you can set it by
setting the env var
export DFBARGS=system=sdl
For example thats how I do it. currently gtk is not passing args
through to directfb.
