Alle my programs are older.
-  My emacs version is 24.1.1, GTK+ Version 2,20.1 and the Ubuntu version is 10 
10.04 LTS Lucid Lynx. And I have libotf 0.9.10, m17n 1.5.5 
-  I installed every program mentioned in the INSTALL-file of emacs -- and a 
lot of other things I don't really remember like emacs-intl-fonts, 
xfonts-intl-arabic...
