The kdesupport-1.1.1-1.i386.rpm in the updates directory
contains /etc/profile.d/kde.csh which contains csh syntax
errors. Possible fix (works for me):

# KDE initialization script (csh)
if ( $?KDEDIR ) then
         if ( $KDEDIR == "/usr" ) then
         exit
         endif
endif
setenv KDEDIR /usr
set kdepath="${KDEDIR}/bin"
echo ${PATH} | grep -q ${kdepath}
if ( $status ) then
  exit
endif

setenv PATH "${kdepath}:${PATH}"
