Hi Bruce Such an error means that linking to the blacs library has not completed succesfully. Please provide your arch.make if we are to help you.
A common error in that link step is that the blacs library is placed wrong in the linking of libraries. Try and read the following basic introduction to the linking step: http://www.network-theory.co.uk/docs/gccintro/gccintro_18.html Furthermore know that Scalapack relies on blacs. Thus blacs should be linked last.
