As all examples are working perfectly in my version of the code I was puzzled by Jeff's issue. It turns out it's a side effect of trying to push as few items as possible instead of just pushing everything in the trunk. I'll fix it in few minutes, meanwhile I'll drop few words about what was the issue.
One might have notice that this framework came without any component. The reason is that all the components in development are still in "paper in progress" stage, and thus not being pushed in the trunk. However, the level of functionality required by the MPI 2.2 standard is provided by the functions in the base, so it will work reasonably well as is. However, it need a "module", otherwise the functions in the base done't have a placeholder to attach to. Thus it is crucial to have a decoy component, one that can provide the empty module to have the base functions copied over. So the problem Jeff noticed was the lack of a basic component in the topo framework. George.
