"autoreconf: not found" error during making qemu-1.4.0
Solution 1:
I just had this problem myself, and the solution I found in reading the autoconf manual which states autoreconf runs autoconf which I did not have installed.
sudo apt-get install autoconf
and the autogen script I am using now works.
Solution 2:
Maybe you can try installing dh-autoconf package.
sudo apt-get install dh-autoconf
