build DirectFB

[Thibaud de Borggraef]

Hello,

I have some problems building DirectFB. It seems it is needed for e17-cvs.
I get this message:

! Problem detected during BUILD
Apparently a problem with gfxdrivers. The question is if I cannot do 
without this module as I have the nvidia driver installed.
