easy_install intbitset That would do pretty well (yum|apt get as well). OR, given the ticket from today about BibRank needing cythonisation; maybe we could just have all the c-extension modules in one place and retrieve them based on the Python version. Such as: from invenio.cmodules import intbitset invenio/cmodules/__init__.py will make sure that only Python2.4 is available if I run Invenio with Python2.4, but I can also put there Python2.6 version and it will work the same While this might not touch all installations, a few people will have the same problems as Benoit. intbitset inside Invenio makes it impossible to run the same code for several sites (or even machines) - on my side it is the search service that uses Solr. Because of intbitset I had to install new Invenio (where I could just run from the existing code base) Cheers! roman > answer in another email (unless someone has a quick solution to Benoit's > problem) > > Cheers! > Sam > > > -- > Samuele Kaplun > Invenio Developer ** <http://invenio-software.org/> > >
