kdewebdev is unfortunately in most parts not yet ready in KDE4. but you can use the KDE3 version inside KDE4. That's how i use Kommander (or Quanta).
I use archlinux, mainly because pacman -Syu gives an allways up-to-date system , but now it's a bit of a problem.
Woulkd it be possible to deinstall only kdewebdev 4.1 and compile kdewebdev 3.5.9 ? I probably would need the
kdelibs 3.5.9 allso isn't it?
thanks in advance
