You can still use require 'korundum4', the difference is that instead of all 
the KDE classes being in a single libsmokekde library they are now split up 
into individual libraries, one for each underlying C++ library. For example, 
there are now libsmokekdecore, libsmokekdeui and libsmokekio Smoke libraries 
that are all loaded by the korundum4 Ruby extension.

The original plan was to split up the Ruby extensions to correspond to the 
smaller Smoke libs for KDE 4.4, but there wasn't time and it will have to wait 
until KDE 4.5 now.

Yes, it should be easier to generate Smoke libraries and Ruby extensions for 
you own C++ classes now. We have a much better Smoke bindings generator, and 
Ruby extensions are fairly simple - I have a simple script I hacked together 
to do that. An explanation of how to do this would be something that would be 
really useful on TechBase.

The idea was to speed things up be making the Smoke classes and Ruby 
extensions both map onto single C++ libraries. We had time to do that for the 
Smoke libraries for KDE 4.4, but didn't have time to split up the Ruby 
extensions. So we won't be able to see any speed increases until the Ruby 
extensions are more modular and you will be able to only load the ones you 
need.

The new Smoke libraries should build on Windows and the Mac, and it may be 
easier than before. I'm not sure what you mean with the question about 
interoperability.

QtRuby/Korundum work with both Ruby 1.8.x and 1.9.x. We need to sort out the 
cmake support to detect and build with Ruby 1.9 though. People have sent 
patches to do it, and we should fix the cmake scripts for KDE asap.

Yes, that sounds a good idea. I recently got the QtText Ruby extension working 
reasonably well, and maybe we could use that for some tests.

Yes, I can help with that perhaps.
