I think you are right. With previous versions of R (until R-2.10.x) I 
did not have this hanging when loading RGtk2 ... And I am pretty sure 
that I have no problems with gtk2 outside of R on my FreeBSD system.

In the meantime I found out that the reported loading error of rggobi is 
a loading error of RGtk2, which fails (hangs). So there remains only a 
loading error with RGtk2. (Because of that I changed the subject.)

After building/installing RGtk2, there are the following messages:

Is there a chance to find out what is wrong with loading RGtk2 on my 
system? Unfortunately I have almost no experience with real debugging 
methods on R. But of course I am willing to help and try out ...
