This is just a feeling, but I think it's just like those non-countable
things like "water". And I can certainly imagine a cook going to the the
butcher's and order a specific number of {Duran lung DIrDu'} so he can
prepare a good dish of {Duran lung DIr}.

If the cook is ordering five pieces of Durani lizard skin from a butcher, it would be {vagh Duran lungmey DIr}, not *{vagh Duran lung DIrDu'}. I don't think the latter is possible, as {DIr} is being used in the sense of a material in this context.

It's like "fur" in English. You don't ask for "five furs", you ask for "five pelts".
