[Robert Sams]

Thank you Duncan. Still no luck, though.

I did...
$. /usr/lib/R/library/RSPython/scripts/RPython.bsh

now i have..
LD_LIBRARY_PATH=/usr/lib/R/lib
PYTHONPATH=/usr/lib/R/library/RSPython/libs:/usr/lib/R/library/RSPython/
Python
R_HOME=/usr/lib/R

but...
$python
import RS

returns the same error. 

And in R...
$R
library(RSPython)
Initialized R-Python interface package.
Warning message: 
the Python callback manager has been registered implicitly using the
defaults (referenceManager())! 

Any other hints? I'm having trouble problem solving this one.
Thanks.
