That seems right, however instead of reworking the Makefile (which is 1250 
lines) I wonder if anyone on this list has an older copy of the HSL 
routines which I could "borrow" (with permission from HSL)?

I am pursuing that as an alternative, but not having much luck with 
dynamic linking. I find that the 1250 line ipopt makefile compiles and 
runs the test programs successfully, but that the 87 line makefile in the 
examples directory does not. So far I haven't been able to figure out the 
difference in the list of library arguments - there is a lot of 
indirection in the the Makefiles that makes them other than 
straightforward.
