Can't install powertop 2.0

[misterBubbles1]

Hi guys,
I tried following the directions to installing powertop 2.0, as described by the readme file

./autogen.sh
./configure
./make
./make install

When I run ./autogen.sh, I get the output

autoreconf: Entering directory `.'
autoreconf: running: autopoint
autoreconf: running: aclocal -I m4
autoreconf: configure.ac: tracing
autoreconf: running: libtoolize --install --copy
autoreconf: running: /usr/bin/autoconf
autoreconf: running: /usr/bin/autoheader
autoreconf: running: automake --add-missing --copy --no-force
autoreconf: Leaving directory `.'

I don't really know what it means. I continue on and run ./configure. Most of the output says yes, but there are some things that say no. I then run ./make. it says

./make: No such file or directory

I do have a Makefile, Makefile.am, and Makefile.in in my powertop directory though.

Why won't ./make run through? Why don't I have a make file?

I am currently using gnome under Ubuntu 12.04.

"make" sure you have the correct permission. (pun intended) i.e. perhaps you need to use sudo.

I tried all the above commands with sudo in front, but there was no change. I'm stuck.

hey actually you have to type the commands like this

./configure

make 

sudo make install
