You can find QAssistantClient in the Qt docs.

Below was from Ulrich Berning. I'd report the bug to Mandrake.

I had the same problen. I guess you have configured Qt-3.1.0 with a prefix and 
called 'make install' after building.

Installing Qt this way strips not only the executables and shared libraries, 
it also strips the archive libraries (qmake is very buggy on install targets, 
it also strips html files and other types of files).

This results in the unresolved symbol when linking.

The solution is to copy the (unstripped) archive libraries from the build 
directory to the target directory by hand after installing.
