So I'm afraid, we need to install it with propagated inputs.

Stimulated by your question I rethought whether we might come around
propagated inputs, and I did not find a solution. There must only be one
version of a library in each profile, otherwise we'd get conflicts. We
could provide our own implementation of site.py (or site-customize.py)
to avoid *propagating*, but this would not avoid the *conflicts* but
only hide the cause of the conflicts and make them hard to find (as we
already discusses a year or two ago).

Sorry for the confusion, this link shouldn't have been there. I had
pasted it in since I thought it is related and I'm going to refer to is,
but it is not.
