Re: openmpi + c++11

Hi Nico,

OpenMPI looks quite a beast to maintain due to the sheer number of 
patches. Updating the source package to the latest upstream version is 
unlikely to be a walk in the park as a result.

I believe your best bet would be to kickstart this effort, ask the list 
when you're stuck, and hope the maintainers eventually join you 
on-board. I could personally find some time to help on a few things, but 
would definitely not be able / willing to do this alone. That's probably 
the case for other people too.

Cheers,
Ghis
