Building kdenetwork (as root) spills out of buildroot and sets
/usr/bin/consolehelper to be suid root (which breaks it entirely).
@(chown root $(bindir)/kppp && chmod 4755 $(bindir)/kppp) || echo "Was
not able to make kppp setuid root"
Since in RH packages, /usr/bin/kppp is a symlink to consolehelper, it is
consolehelper that gets the suid root. The GTK+ libs that consolehelper uses
tend to have a fit and exit when running suid root, so this more or less wrecks
consolehelper and the 50 or so tools that use it.
I know that one should be careful building rpms as root, but that I also think
that packages should build as cleanly as possible. Also, we don't exactly make
it easy for customers to build rpms as nonroot. The default setup leans heavily
towards building as root in /usr/src/redhat.

It's fixed in 3.1-0.5 or newer.
