You must be speaking about the source code installer ?
I tried installation of that, and it fails miserably for some reason on mandrake-mandriva systems : I searched a thread about that on linuxquestions.org and it can only be solved on home-compiled KDEs
But all's not lost !
After a long time searching mirrors, I finally found an RPM for an old version of Wnck, whith the right .so* file, and installed it.
And guess what, now ?
Now it's another RPM that is required !
As before, it's another version of an already-installed RPM, libxerces-c.
My own version is libxerces-c26, but alas it's libxerces-c25 that is required.
Guess what, I can't find any RPM for that one, except on Mandriva Club mirrors, but of course I don't have a Club account.
Let's halt the problem study for the moment, i'll see first if I can a Club member to kindly offer me just that precise RPM, if possible. If so, or at least I hope, the problem will be solved...
