I reported this already under: dojo/interop#36
but this bug tracker seems not to be very active, so I am cross posting it here.

Both, the sample code and the setup from the turorial: https://dojo.io/tutorials/1040_dojo1_dijits/
and the docs: https://dojo.io/docs/index.html#doc--dojo__interop__v2_0_0
give me the error:
Module build failed: ReferenceError: define is not defined
