Check out #51 for the changes that need to be made. I'll be creating a new PR that can be merged with this code over the weekend to fix the dev build craft versions.

ok will there be a new version coming out with the fix

I would guess not until build craft has a new official build, but that's up to steven

Yes, my builds are only compatible with official BC releases.
