'fancy hacks':
* I don't bother for the lack of respect (I know I do fancy hacks anyhow, so I remain unfazed ;-)
* the point is, OK, how should we share the experience of customizing the MPI stacks? I really think that users of EasyBuild ("social sysadmins") would like to share such information.

And if there is a better way to do so than the proposed patch, I'm totally eager to hear that...
