Prawn + PrawnTo + Rails 2.3.2

Hi,
Have anyone made a successful usage of Rails 2.3.3 with PrawnTo and
Prawn ?
I followed all the tutorials I could find on Net, but I am not able to
see pdf part working.
I kept getting the error “Template is missing”. I do have foo.pdf.prawn.

Same goes with pdf/writer as well.

Thank you.
