Hello Nicholas,

> After trying to install kranc unsuccessfully, I tried a few things and
> eventually got an installation success message, but now when I go to build
> the Einstein Toolkit with the new thorns I get hit with an error about
> being "undefined reference MPI::Comm:Comm" in a few places in whichever
> thorn the ET is currently on while compiling, with removing a problematic
> thorn from the thornlist just postponing the error. From what I can find
> from some digging and looking, it seems to be a linking issue but I am lost
> after that.
