[petsc-users] Open MPI library version error

[Daniel Stone]

Hi Pierre,

I'm using 3.12.2, which is a bit old, but needed for the Pflotran version
I'm using. It certainly predates that merge.

Many thanks for pointing me to that merge - if nothing else I could now
study that and try manually implementing
it to see if it helps my situation.

Thanks,

Daniel
