That file does not exist. Can I simply downoad that file from somewhere and 
put it into that directory? Or do I have to replace one of the installed 
packages by a new version (that includes that file)? On my system I have:

at-spi-1.0.0-208
atk-1.0.3-45, atk-devel-1.0.3-45
bonobo-1.0.20-167, bonobo-devel-1.0.20-167
bonobo-activation-1.0.2-115, bonobo-activation-devel-1.0.2-115
libbonobo-2.0.0-165, libbonobo-devel-2.0.0-165
bonobo-conf-0.14-450
libbonoboui-2.0.1-58, libbonoboui-devel-2.0.1-58

(As stated some mail earlier, a full list of packages is in 
http://www.schmi-dt.de/rpm.txt)

Well, at the moment it seems that we do not immediately need GOK. Our mother 
has some illness which slowly makes the nerves disappear. As a result of that 
she will be able to do less as the time continues. Her consciousness is not 
affected by that illness.

Since two weeks she is in hospital. There they have done some operation for 
facilitating breathing. After that operation she could only use one hand. 
However, that was only some aftereffect of the operation. Now she can 
actually use a normal keyboard.

However, there will come be some time when she can only use one hand, and 
later there will be some time (at the very end) when she can only move her 
eyes...

Well, before she went to hospital she used KDE and KMouth, so our approach 
would have been to use the GOK as an input device under KDE. However, KDE is 
currently not accessible in such a way as GNOME is. However, I hope that we 
are able to add AT-SPI code to KDE in the near future, so that it is both 
possible to use GOK with good results under KDE and to use KMouth under 
GNOME. I do not see any reason why we need some application "GMouth" besides 
KMouth or some application "KOK" besides "GOK".
