0.8.2 is our current reference because, AFAICT, it is the last version of rpy2 that supports Python2. If/when our plans to switch to Python3 succed (at last !), we should explore its newer versions.

Depending on one set (or possibly a coice of sets) of numerical libraries would allow us to get rid of them in Sage-the-distribution, which should lighten it considerably...
