A bit further trying to see what's wrong it seems that Python is
failing to load .so libraries for some reason on the system where it
doesn't work.

The initialisation code in the evolution module has:-

    import ebook

So, obviously this works on the old system but not on the new system. 
The ebook.so file is present on both systems in exactly the same place.
