Well, it doesn't explain it ;(  Yoz has persuaded Search::Xapian to load the
correct libxapian.so in.  It still goes wrong in the same way before.  
Even though it is loading the right library (I've double checked this
with ktrace):

baked:~/fawkes/search$ ldd /usr/local/lib/perl5/site_perl/5.8.2/mach/auto/Search/Xapian/Xapian.so
/usr/local/lib/perl5/site_perl/5.8.2/mach/auto/Search/Xapian/Xapian.so:
        libxapianqueryparser.so.3 => /usr/local/lib/libxapianqueryparser.so.3 (0x28147000)
        libxapian.so.3 => /usr/local/lib/libxapian.so.3 (0x2815e000)
        libstdc++.so.3 => /usr/lib/libstdc++.so.3 (0x2833c000)
        libm.so.2 => /usr/lib/libm.so.2 (0x28381000)

Any other suggestions for debugging this?

Summary so far:
- On our server (FreeBSD), when making a database with the Perl bindings, it
comes out corrupted with all weightings having the value 0.
- With the same scripts, same version of Xapian, on my laptop it works fine.

I'm sure there is something wrong with the way stuff is installed...  But
I don't know how to work out what.
