This turned out to be crucial in debugging:

The problem with "guix build soprano" was not in the patch of soprano
(which was there), but of its input clucene; with the more informative
error message, we found the problem together with Ludovic: A few patches
were there in git, but not added to gnu-system.am. So they were not
installed by "make install".

This is corrected in commit 2dfed64.
