[Users] Problem with tutorial

[Roland Haas]

Hello Julia,

> I am new to the Einstein toolkit, so I wanted to go through the tutorial first. Unfortunately, I do not get beyond the step of building the Einstein toolkit:

Hmm, that is a linker error. My guess would be that one needs to
explicitly list the C++ bindings for MPI in the linker library list. 

This should of course work automatically, but clearly is not anymore.

In particular on the ET maintained tutorial server it should just work.
Since it is not, we will have to fix the server and the code.

Let me try and see and get back to you.

Yours,
Roland
