Playing devil's advocate I should remark that first each language is building
its own repository and packaging system in a sense we have lots of equivalents
of (yum+rpm) for each language (perl, php, python, R, tex, ...).
On the other hand for the system to be really useful it must use the least
possible denominator (read the dumbest wins- pun intended ;-) ).

I am not sure if this is right path or the right balance.
Another possible choice is to expand R2spec in scope and not only create rpm
spec files but to discover the different dependencies and how they are solved
There is no reason that we can not rebuild the whole CRAN (or almost all of

As everything with free software the survival of the fittest means that this
will only happen if there are people interested in spending resources to make
