Your system is using atspi2, then, rather than atspi. You should, therefore, be 
using the atspi2 screen driver.

>How do I use AtsSpi2 instead AtsSpi if the error is because of that?

-x a2

The atspi2 screen driver is only built if two conditions are both met. The 
first is that you have the dbus-1 package installed, and if its version is
greater than or equal to 1.0. The second is that the <X11/keysym.h> header can 
be found. You should find it in a package named something like
xorg-x11-proto-dev.

Yes, that makes sense. I believe you said that you're only interested in using 
BrlAPI, and that you're not, at least for the time being, interested in 
BRLTTY's screen reading capabilities. In that case, you don't need a screen 
driver.
