I tried using ucycle directly from Data.Graph.Inductive.Example by itself.

I didn't realize there were two instances of Graph. How would you use the PatriciaTree Graph instance in the ucycle type signature?

ucycle :: Graph gr => Int -> gr () ()

You must have that Graph instance in scope. I can't give any more suggestions as I don't see the code in which you use `ucycle`.
