That doesn't seem to be it:

ie it still fails.

I was a little afraid of this.  RPy has _long_ been dead. I even patched it
for (IIRC) R 2.10 when the original version regexp could not deal with two digits.

Could you spend some time on it?  I don't personally use it, and as we have
RPy2 actively maintained, would otherwise suggest to just drop it...

That thread is about RPy2, not RPy.  

I suspect that R 3.0.0 simply removed Rf_PrintWarnings and we'd have to
recode this.
