[vtkusers] vtkqt1.7.2 compile problem

[kavec at messi.uku.fi]

Hello, 

I am trying to compile vtkqt1.7.2 on Gentoo linux using gcc-3.3.4. I downloaded
VTK from cvs last Monday. I have qt-3.3.4. Compilation stop with following error:

***************************************

*****************************************

The vtkqt1.7.2 package contains several folders, I assume for different VTK
versions. I chose the most recent one, VTK_4.4. and I used "CMakeList
Examples/CMakeList2.txt" to generate Makefile.

Any help is greatly appreciated.
