Installatin root on kubuntu

hi,
i download and install root_v5.11.06.source to my PC a few hours ago. it was SLC4 and i hadn’t any problem. i can use root on my PC now.
but when i try to install root to my laptop (which is Kubuntu on) i have some problem. first error was “x11-devel package must be installed”. ok i solved the problem by installing these packages via synaptic. and then i write “./configure linux” in root directory. here is the config.log;

and i write make (i have tried gmake). but the error is
bash: gmake: command not found
bash: make: command not found
