| There is an issue with python-rpy on Ubuntu, when installed from the

| package is experimental but you are happy to receive feedback on it.)
| After adding the appropriate CRAN repo:
| 
| % sudo apt-get install python-rpy
| [ ... installs various dependencies ... ]
| % echo import rpy | python
| RuntimeError: No module named _rpy2151

|       RPy module can not be imported. Please check if your rpy
|       installation supports R 2.15.1. If you have multiple R versions
|       installed, you may need to set RHOME before importing rpy. For
|       example:
|   
|       >>> from rpy_options import set_options
|       >>> set_options(RHOME='c:/progra~1/r/rw2011/')
|       >>> from rpy import *
|       
| 
| This is simply because the module needs recompiling with each new R release:
| 
| % apt-get -b source python-rpy
| % sudo dpkg -i *.deb

Yes, there is code in the package which hardcodes the then-current
version. It is a pretty brain-dead scheme as it forces a rebuild on
major.minor changes.

| And it all works fine.
| 
| Would it be possible to get this module rebuilt automatically in line
| with new releases of r-base-core?  Right now I have to hold back updates

Your maintainer is guilty as charged. This time I simply forgot to rebuild rpy.
