[Kip Koon]

I use ded quite a bit since I can't change anything in the repo and expect it to appear in my rebuild.

Hi Chris,

I followed your suggestion, and the MPI code in the clock2_disto4 module is now included, but the MPI.Slot value is set to 2 as if the makefile's value is ignored and the value from coco.d is used, but is being decreased by 1.

Sigh. I guess I can use dEd to fix it, but.... :(
