Adding spline<2> typekit makes ruby layer fail

[jmachowinski]

Hey,
after I added a typekit for spline<2> (see jmachowinski@a0538e2 ) my ruby layer fails with the error :
/home/scotch/spacebot/install/lib/ruby/1.9.1/typelib/registry.rb:289:in `block in export_to_ruby': there is a type registered at Types::Base::Geometry::Spline::VectorT which differs from the one in the registry, and override is false (Typelib::Registry::InconsistentTypeExport)

Ideas on this one ?
