Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:          Linux

I have used the below method to build the latest KDE etc from CVS.
It all went great except for the final package kdevelop.
(All other packages build/installed fine and I've been using them just fine).
The error I'm seeing during the "make >& make.log" for kdevelop is below.
