Gamma 6.7 - 6.6 : no ShaderNode<float32>

Hello there
when I open help patches in 6.7, there are these red links saying no ShaderNode for simple value boxes… in bool, float, int
is there something I did not install on the way?
any ideas?

assuming it is the same issue as solved over here? Gamma 7.0 help browser - how to : they don't open? - #2 by joreg
