Hello,
Maybe someone could use this oneliner shell script for porting from forge 4.x -> 5.0 which replaces the deprecated getOrCreate... functions.
It solved 56 of 60 buildcraft build errors.

On FreeBSD 9 it's runs with with Forge #275.
You need to install two packages: openjdk7 and xorg-fonts-truetype
Then the server starts with:
java -Djava.awt.headless=true -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
I hope that this helps you out.
