It's bogus. There is no SWIG_TypeQuery. There is definitely something
wrong with your build.

The latter one is what's supposed to be there.

I imagine that something isn't building correctly on your system. I've
compiled both the 1.1.1 and the trunk/ bindings, and they compile and
work just fine on my box.

Can you provide more information about the machine your trying to compile
on? Which OS? Which version of SWIG? IIRC, I saw another post where
you had tried a couple of different versions. Perhaps, there is some
left over crud for the previous SWIG version that's causing a failure?

FWIW, I'm running SuSE 9.1, which has SWIG 1.3.21 and Python 2.3.3. I've
also got this running on SuSE 9.2, which has SWIG 1.3.21 and Python
