I may be missing something but I thought I'd point it out in case anyone has an issue.. this could go here or installation issue:
>Synopsis: repocopy: move net/rrdtool to databases/rrdtool

If your having trouble installing rrdtool from the toaster setup, manually install the port then complete the setup.
