That clears things up for me a bit, so here is some general advice I hope can help:
You cannot use buildr without a Buildfile - except if you use the buildr task to generate one. Buildr has a builtin task to create a Buildfile from a pom.xml file, just go buildr -T for more information. You cannot use buildr within a ruby script. Buildr is packaged as an application and expects to behave in that setting. If you are interested in using a specific functionality of Buildr, like reading pom files, you probably will have to fork or require some of the buildr ruby files individually.
