[galaxy-dev] rpy vs rpy2

I'm trying to install rpy for Galaxy, however it seems to not be available anymore. rpy2 is supposed to be the replacement. Does/will Galaxy migrate to rpy2? Some of the tools rely on rpy but since its not available anymore, the tools can't run. Also, why use a R python wrapper? Why not just create an R script and run 'Rscript' directly? Ryan
