1.6rc3 ctypes python test suite

Is this supposed to work correctly with python 2.6? (ctypesgen rev 63):

$ make check-ctypes-python
cd /home/users/arekm/rpm/BUILD/subversion-1.6.0-rc3/subversion/bindings/ctypes-python; \
          /bin/sh /home/users/arekm/rpm/BUILD/subversion-1.6.0-rc3/libtool --tag=CC --silent --mode=execute `for f in /home/users/arekm/rpm/BUILD/subversion-1.6.0-rc3/subversion/*/*.la; do echo -dlopen $f; done`
/usr/bin/python setup.py build --subversion="/usr" \
          --apr="/usr" --apr-util="/usr" \
          --ctypesgen="/usr/bin/ctypesgen.py" --svn-headers="/home/users/arekm/rpm/BUILD/subversion-1.6.0-rc3/subversion/include" \
          --cppflags="-D_FORTIFY_SOURCE=2 -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -I/usr/include/apr -I/usr/include/apr-util -I/usr/include -DQT_SHARED -D_REENTRANT -DQT_CORE_LIB -
