Some Galaxy tools failed to import rpy module and displays the following message:

Traceback (most recent call last):
 File "/usr/local/bioinfo/src/galaxy/galaxy-dist/tools/plotting/histogram.py", line 
5, in <module>
   from rpy import *
ImportError: No module named rpy

For instance, the tool "Regrouping" (tools/stats/grouping.py) have been refactored in 2011 by Kanwei Li to use numpy instead of rpy. And this tool runs on my local instance of Galaxy. But I would like to be able use rpy module instead of refactor the others tools.

Could you, please, help me to understand why the eggs ' import does not allow the use of rpy module? How to debug these tools?

Thnaks in advance,
