autoconf: command not found

There are or were some tools that Ubuntu needs to do basic compilation.

I have a note that says:

sudo apt-get install build-essential automake autoconf libtool
libncurses5-dev (to use menuconfig)

I have a line through autoconf.

I would try:

sudo apt-get install build-essential first and see if things improve.

I had this exact problem, and I finally found the answer. You need to
install GNU autotools. On Fedora 16 this was included with automake
package. 

$ yum install automake

Just search GNU autotools your OS for the package to install.
