I had a go at it, but did not succeed to produce a working python-
singledispatch package. After installing python3-all and python3-setuptools 
outside the pbuilder chroot (!) I could build a .deb, but this mysteriously 
depends on a virtual package python-ordereddict which is not in Debian and I 
do not know what package should provide that. As I do not understand how these 
python dependencies work, I stopped there.

I did successfully install rpy2 in the presence of 3.2.0 from CRAN in a wheezy 
chroot, using pip install. You need to install the development files for R, 
python and readline as well, compare the rpy2 installation instructions.

If someone can give me a hand here, OK, otherwise I will have to remove 
python-rpy2 from the wheezy-cran3 and squeeze-cran3 repositories (there it 
does not work either I found). I did not notice as I do not currently use 
rpy2.

Kind regards,

Johannes
