GTK+_failed installation

[Nabil Ferguen <nabil ferguen gmail com>]

Dear Team GTK,

I would like to install gtk+ (for OOF2D) on ubunto 12.04, and I have successfully installed all packages (pango, glib, gdk-pixbuf, atk) but the compiler fails and sends an error message linked to the atspi-2 package (requires version > = 2.11.2). I have looked on the web in order to find this package but it seems that it is obsolete. How I can fix
this problem.

Yours sincerely,

Nabil Ferguen
