I think now I partially understand what's happening. To build the 1.9 version 
of qtruby, I also neeeded to rebuild and reinstall smoke. The new smoke 
version was installed in /usr/local/lib, while the old one was in 
/usr/kde/svn/lib. The 1.9 version of qtruby was installed in 
/usr/local/lib/ruby19/site_ruby/1.9.1. 

It seems that the new version of smoke is loaded even from the 1.8 version of 
qtruby, most likely because /usr/local/lib comes before /usr/kde/svn/lib in my 
load path. What I can't understand is why the new version of smoke isn't 
compatible with the 1.8 qtruby. I thought that smoke itself had nothing to do 
with ruby and so it would have been the same for both ruby versions. It seems 
clear that it's not so. Has it something to do with lines like 

Set runtime path of "/usr/kde/svn/lib/libsmokekde.so.2.0.0" to 
"/usr/kde/svn/lib:/usr/lib/qt4:/usr/kde/svn/lib"

which I see during the install phase? If so, what do those lines do?

Thanks
