Neil,

PANOPTICODE = ["org.panopticode:panopticode:jar:0.1",

# This leads to an array with full paths to PANOPTICODE jars.
PANTOPTICODE_CLASSPATH = PANOPTICODE.map { |spec| artifact(spec).to_s }

Here's my second question:

The 'somemethod' is being declared on the 'main' object, thus it has no
access to the current project methods (like path_to), you either have to
pass the project as
an argument or define the method on the current project object:

def self.somemethod
  path_to("usr", "local", "bin")
end

If you have more than one simple method, prefer defining a module and
extending the current project with it.

Best Regards,
