Hi Roman. I recently implemented something similar to what you proposed for the ADS Python libraries. We have 3 C modules that need to be made available for different architectures and versions of Python.
Here is the implementation for the Looker module: https://github.com/badzil/ADS-Python/blob/master/Looker.py Something similar could probably be done for Invenio. Benoit.

Because of > intbitset I had to install new Invenio (where I could just run from > the existing code base) I recently implemented something very similar to what you propose. In the ADS Python libs, we have 3 C modules that need to be made available for different computer architectures and versions of Python. The problem is similar to the one we're discussing as the modules are included in the Python libraries and at first it was possible to run them only with one version of Python. Here is the implementation for one of the C-module: https://github.com/badzil/ADS-Python/blob/master/Looker.py And the installation script for the C modules: https://github.com/badzil/ADS-Python/blob/master/ads_c_modules/src/setup.py You might also want to take a look at the utilities to determine platform and Python version: https://github.com/badzil/ADS-Python/blob/master/ads_c_modules/utils.py -- Benoit Thiell The SAO/NASA Astrophysics Data System http://adswww.harvard.edu/
