Now, within the newly created vmware-system, I first installed kubuntu 7.04 to have something easy to start with.
Within this system, I will try out KDE4, as I am very interested in the new look and feel and everything. 
There are nice tutorials over at kde.org – for today, ‘ll use the “anonymous svn” tutorial, as I have never worked with this tool (there is also an extremly useful “getting started with svn” tutorial there)
I installed kdesvn and added the svn://anonsvn.kde.org/home/kde bookmark. Then, I had a loot at the KDE4 installation tutorial at kde.org. I install the packages given, but I will build qt and cmake later, but I also installed graphviz and kdesdk-scripts (for makeobj).
Next step is to create an extra user – although it is only in a vmware-environment, this can come in handy when things break. I created a .bashrc as given. Finally, we make sure that kde-devel, the new user, has /bin/bash as its shell (sudo usermod -s /bin/bash kde-devel).
As a test, I am going to install latest d-bus – as described. This works – so it seems I am ready to go on and install kde4. I’ll post any unusual stuff here (and experiences too, of course…)
