Hello Manuel,

Yep, it is. The trick here is that I am doing the same thing as before.
I am just taking the static libraries to include them into
libopenmpi-dev.

Well, I took the idea from gromacs but I don't see what you are talking about in the current package.
In gromacs 3.3.3-3, they don't do the way you describe. They are
building it many time [1].

I believe this issue fixed this way. I need to test it deeper.

It is my feeling ;). My goal here is to address ""lambda users"" trying
to provide the actual static libraries in the -dev package without
changing the behaviour of the dyn libraries.

No emergency !

Thanks for your feedback.
