Does that apply when using dlopen?
When python dlopens _xapian.so, something automatically knows to
load libxapian.so.8.0 too - so there's definitely a working shared
library dependency mechanism in this case.
The bottom line for me is that if I explicitly add "-lstdc++" when
linking _xapian.so, it all works. If I don't, it doesn't. So I
kind of feel that ideally libtool should be doing that for me...

It definitely isn't doing that. This is what I have in _xapian.la:
dependency_libs=' /home/olly/install/lib/libxapian.la'
But unless python uses ltdl that wouldn't help me here anyway.
