I've had this laying around locally for a while. binutils was not working so I didn't feel like this was worth pushing. My new stdio FILE buffering rewrite fixed binutils and now gcc actually works!
Ports
Here are all of the ports for banan-os.
Building
Run the build script in the directory of the wanted port.
cd ports/<port name>
./build.sh
Port will be installed to the disk image and is usable when running banan-os for the next time.
