yes. well it pays to read carefully.

once i fixed it in the top level module another module also be called had the wrong import, i didn't notice that at first, thought i had the same error. well i did, but in a different file.

all fixed and i'm good to go.

thanks for your help !

p.s.  is there documentation that makes it clear that Data.Complex is required ?

I'm looking at the haskell hierarchial libraries and it's not at all obvious that Complex comes under Data.  Here's the link I'm using:
