Couldn't detect type of database

[Jim Lynch]

Hi, Olly,

I have no idea what was going on.  I installed xapian from Ubuntu repos 
and had the issue.  xapian-delve and xapian-check gave me the same 
errors.  I've now build the libs and perl bindings from source and all 
is well.  I do not know, but I'm happy it's working again.

Thanks,
Jim.
