With '--no-test-load' it installs and ends normal. Loading per 
dyn.load("RGtk2.so") works, just as dyn.load("RGtk2.so",F) and 
dyn.load("RGtk2.so",,F). Unloading works, too.

Normal loading over library(RGtk2) within R does not work. R than is 

It seems the problem is not with the library itself?

I moved to R-devel.

I am using RGtk2_2.12.18.tar.gz for month now.
