Thanks for the tip, but it did not fix the problem:
$ svnadmin verify /var/lib/svn/repository svnadmin: Berkeley DB error for filesystem '/var/lib/svn/repository/db' while opening environment:
svnadmin: DB_VERSION_MISMATCH: Database environment version mismatch svnadmin: bdb: Build signature doesn't match environment
Looks like all it has done is rephrased the error message.
