 Ok, now I've found out about environment modules. It isn't about openmpi
only, but something more general.
 Interesting information is at:

 http://www.urc.uncc.edu/urc/cluster-utilities/environment-modules/

 With 'module load openmpi-x86_64' before building, now the build works
perfectly.

 I hope this can help other people who might be as confused as I was :)

 Thanks a lot,

 Juan

 You might want to ask on a Fedora mailing list what's the correct way
 to select an "environment module" with their new package. I think
 this has nothing to
 do with the Boost build process -- you probably just need to set some
 environment
 variables or run a command that does some kind of environment setup for
you.

 I don't use Fedora myself and I have no access to any machine running
 it, so I'm afraid I cannot be of any help here.

 Best regards,
 Riccardo
