Yeah, I found you can fix that by passing "-feature _xapian" when
running SWIG.  The documentation wasn't clear, so I compared the
generated file with and without, and this only affects the "Init_XXX"
symbol.

Yes - I don't think I said explicitly, but with the patch "make check"
passes for Ruby for me.

Incidentally, it might be worth the effort of installing 1.3.29 - SWIG
gained a "magic renaming" thing added for Ruby pretty recently which
might be useful to us.

So I noticed.  That's fine for now, but less good generally since
dynamically loadable modules don't have a ".so" extension on every
platform (it can be ".dll" or ".sl" or probably other things).
