think Alex has released a version for 0.8.1 yet, though 0.8.0.X should
work apart from a new API method and possibly a few unused Error classes

Ah, that I can answer:

delve doesn't run queries - it's trying to open a database called
'treatment OR centre'.  If you want to try queries, run quest.

It'd be more helpful if it included the database name in that error

If it's Linux, look in /proc/<pid>/maps for a perl process such as:

perl -e 'use Search::Xapian; sleep 99999'

That should show which Xapian library is being loaded.
