autoconfig autoheader not found

In attempting to build Pike 8.0 I was met with a slew of errors. I used the make command as specified.

the errors begin...

cd src && ./run_autoconfig . ./run_autoconfig: 1: ./run_autoconfig: autoconf: not found ./run_autoconfig: 70: [: Illegal number: Warning: Using autoconf < 2.50. Don't do this if you want to make export.

followed by a hundred or so lines of

./run_autoconfig: 139: ./run_autoconfig: autoheader: not found ./run_autoconfig: 143: ./run_autoconfig: Running autoconf in .

with variations on the path.

I was successfully able to build Pike 7.8 and play around with it using the same method. Can any body provide any advice to get me up and running? I'm running Linux Mint 17 Qiana 32 bit XFCE.
