$ wget http://www.omegahat.org/RSPython/RSPython_0.5-1.tar.gz |
Then install RSPython in R:
# R CMD INSTALL --clean RSPython_0.5-1.tar.gz |
This command, executed as the root user has then installed the required files into /usr/lib/R/library/RSPython. To communicate where the files are installed to Python we need to set up three environment variables (a Debian package would probably set this up so that these extra environment variables are not required), and then run Python and try out some RSPython calls:
$ export R_HOME=/usr/lib/R
$ export PYTHONPATH=${R_HOME}/library/RSPython/Python
$ export PYTHONPATH=${PYTHONPATH}:${R_HOME}/library/RSPython/libs
$ export LD_LIBRARY_PATH=${R_HOME}/bin
$ python

If you get:
$ python
>>> import RS
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/R/library/RSPython/Python/RS.py", line 1, in ?
import RSInternal

Then be sure that you don't have atlas2-base installed:
$ wajig remove atlas2-base |
