You don't want make modules install, you want make modules_install, as
in <http://www.tldp.org/HOWTO/Kernel-HOWTO-2.html#ss2.2>.

If you are using debian, all you have to do is

apt-get install kernel-package libc-dev gcc debianutils make \
libdb3-dev libncurses-dev fakeroot 

go to your linux kernel source directory, do

make xconfig

and

fakeroot make-kpkg clean ; fakeroot make-kpkg kernel_image --revision mykernel.01

This will build a .deb in the parent directory that contains the kernel
and all modules that you can install with dpkg -i.
