Solution to this problem is:
sudo apt-get install autoconf
Thanks@Zelek Uther
Didn't know that this doesn't come preinstalled with the Raspbian Distro for the Banana Pi. Now there are some new errors so I have to google some more...
You're welcome Lincoln6Echo.
Good to see more nodes running on cheap single-board computers.
Be a seeder not a leecher, be sure to forward port 8333 to your Banana Pi (if you only have 8 connections you are not contributing).
G'luck getting it up and running. Maybe start a "how-to" thread for the Banana Pi once you have it working.
At the moment I got the Banana Pi compiling.
Hope the result will be fine. As soon as possible I will start a ''how-to'' for the Banana PI. I think BPI is more suitable for the job than the RPI because of the SATA port. Well, we see...
