Keith is correct. Gropdf fails to handle the "-I switch", the reason is 
because it is not expecting groff to pass the switch on to gropdf. It needs to 
pass the switch to grops because it affects the searching for eps files, which 
gropdf does not accept.

I will add code to ignore the switch in future, or use it to search for pdfs 
which are to be imbedded. Thanks for the heads up.
