[Kde-bindings] is it possible to use qtruby4 with ruby 1.9?

Following your suggestion, I tried to make sure to have everything up to date. 
After installing the latest SVN revision of KDE, I did the following:

- removed all things related to qtruby4/korundum4 both with a make uninstall 
and with a manual search for pieces which could have remained behind
- removed the kdebindings source trees and the build directories
- checked out the latest svn revision of kdebindings
- created a build directory for the 1.8 version of qtruby
- cd in the build directory
- run cmake then ccmake to change the install prefix from /usr/local to 
/usr/kde/svn
- run make and make install

This installed a completely working qtruby4/korundum4 for ruby 1.8 (in 
/usr/lib/ruby/site_ruby/1.8/). It also installed smoke in /usr/kde/svn/lib.

I then did the following to build the bindings for ruby 1.9:
- created a build directory (different from the one for ruby 1.8)
- cd in the build directory
- run cmake
- with ccmake, changed the following things:
 * disabled smoke (hoping to force linking with the already installed smoke)
 * changed the installation prefix to /usr/kde/svn
 * set the CUSTOM_RUBY_SITE_ARCH_DIR and CUSTOM_RUBY_SITE_LIB_DIR to
   /usr/local/lib/ruby19/site_ruby/1.9.1/i686-linux and 
   /usr/local/lib/ruby19/site_ruby/1.9.1/ respectively
 * changed the RUBY_EXECUTABLE variable to /usr/local/bin/ruby19
 * changed the RUBY_INCLUDE_PATH variable to /usr/local/include/ruby19-1.9.1
 * changed the RUBY_LIBRARY variable to /usr/local/lib/ruby19.so
- issued the make command
The result was a linking error, with the message included in the 
qtruby_compile_error attachment.

I tried copying the lib directory from the compilation of the 1.8 version to 
the build directory for the 1.9 version, but nothing changed.

To make the version for ruby 1.9 compile, I needed to also compile smoke. 
After installing it, however, the 1.8 version stopped working.

The command ruby -rQt4 -e 'Qt::Application.new []' produced a crash. The 
backtrace, from gdb, is in the crash1 attachment.

As I already said in my previous mail, I suspected that some library for the 
1.9 version was loaded from the 1.8 version, so I tried changing my 
LD_LIBRARY_PATH and LDPATH to make /usr/lib come before /usr/local/lib. Then I 
tried: the previous command. The result was:

/usr/lib/ruby/site_ruby/1.8/i686-linux/qtruby4.so: 
/usr/kde/svn/lib/libqtruby4shared.so.2: undefined symbol: _ZN5Smoke8classMapE 
- /usr/lib/ruby/site_ruby/1.8/i686-linux/qtruby4.so (LoadError)
        from /usr/lib/ruby/site_ruby/1.8/Qt.rb:1

This happens with qt-4.4.2, the latest svn revisions of kde and kdebindings,
ruby-1.8.7-p72, ruby-1.9.1-p0 and gcc 4.3.3.

I can't understand what's happening. Do you have any suggestion?

Thanks

Stefano
