Yes, that's the symptom.

In maintainer mode, the configure script for xapian-bindings should
check your swig version is suitable and disable PHP if it isn't.  You
can also specify 2 different swig versions.  Except I haven't checked
that change in yet (cough).

Try "cvs update", "make configure" in xapian-bindings, then configure
the bindings with:

./configure --enable-maintainer-mode SWIG_1_3_22=/path/to/swig-1.3.22

On ixion, I have SWIG 1.3.22 installed as /u1/olly/install/bin/swig-1.3.22

We should probably run swig with -Werror now that we're running it when
we build the release tarball rather than on the end user's machine.

The issue is they enabled some threading stuff in zend, which changes
the zend API slightly.  You're meant to use magic macros which expand to
nothing in the non-threaded case, but SWIG generates PHP without the
required macro in one place.

Doesn't sound like this is your problem though.
