When configuring accerciser from outside source dir, such as by using jhbuild with 'buildroot' set, it tries to call "./configure" at the build dir, after successfully calling autotools at source dir. This fails because "configure" is generated at source dir, not build dir, and it should be invoked with source dir path prefix.

With autogen.sh providing proper $srcdir, gnome-autogen.sh should invoke configure at the correct path.
