Here is another route: I just disable (!!) the PrintWarnings() calls (that
want the no-longer-exported Rf_PrintWarnings() function:

And now things work:

edd at max:~/svn/rpy$ python 
Python 2.7.3 (default, Sep 26 2012, 21:51:14) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import rpy
>>> 

Shall we do that?
