First of all, the libraries inside the LSB do not have to obey LSB itself. 
What matters is that those libraries be present in the target system, 
providing the interfaces that LSB requires them to.

How they go about accomplishing that is not part of the standard.

Second, the standardised version of GTK is pretty old. It links to libX11, not 
to libxcb.
