What I must install to start developing in gnome accessibility?

["Carlos Eduardo R. Diógenes" <cerdiogenes yahoo com br>]

I thinked in update GNOME, Kernel, GCC, GDB and X.ORG?
There is something else that I must update to work
with the accessibility project?

Is better to use the stable sources, or I must take
some packages from CVS?

Thanks,

Carlos Eduardo.
