   Jed,  I made this change but it makes everything useless because 
pkg-config PETSc --libs
-L/Users/barrysmith/Src/petsc-dev/arch-opt/lib -lpetsc  

how are people suppose to know what libraries to link against? Note that 

pkg-config PETSc --variable=Libs.private
returns nothing so how the hey does one get this information? 

I'll need to revert without a good answer.
