Hi Anne
Thanks so much for answering.
I did try and both, system and/or QGIS Python version are the same: 2.6.5.
Then I tried the import rpy2.robjects as ro in the python console of QGIS but 
I do not understand the type of error. This is the outcomming text from the 
Kconsole or the Python console of QGIS:

>>> import rpy2 as rpy2
>>> import rpy2.robjects as ro
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/share/qgis/python/qgis/utils.py", line 291, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
  File "/usr/local/lib64/python2.6/site-packages/rpy2/robjects/__init__.py", 
line 12, in <module>
    import rpy2.rinterface as rinterface
  File "/usr/share/qgis/python/qgis/utils.py", line 291, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
  File "/usr/local/lib64/python2.6/site-packages/rpy2/rinterface/__init__.py", 
line 66, in <module>
    from rpy2.rinterface.rinterface import *
  File "/usr/share/qgis/python/qgis/utils.py", line 291, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
ImportError: /usr/lib64/R/lib/libRlapack.so: undefined symbol: 
_gfortran_concat_string 

I do not know where to go from here...
thanks,
Gian Paolo
