Hi,
Glad you got the plugin going.
Part of the problem is these aren't class methods, but rather instance methods.
I would reccomend alias_method_chain[1] to extend medium_uri itself, instead of
trying to get down into the interpolate_medium_vars method.
Something like this should do:
module AddBuildId
module HostExtensions
extend ActiveSupport::Concern
included do
alias_method_chain :medium_uri, :build_id
end
def medium_uri_with_build_id(host, url = nil)
medium_uri_without_build_id(host, url).gsub('$buildid', host.buildid)
end
end
end

And within the engine.rb loading it via:

Operatingsystem.send(:include, AddBuildId::HostExtensions)
but it is not doing what I want still. Any suggestions would be greatly
appreciated.
Thanks,
