I think this error comes from the fact that the jupyter package is
missing as native input, therefore the 'jupyter ...' command can't work.

It lools like the 'install-kernelspec' phase just copies the kernel you
generated in "share/cl-jupyter/kernelspec/" to
"share/jupyter/kernels/cl-jupyter/". Wouldn't it be easier to generate
the kernel in the final directory directly? Then the
'install-kernelspec' phase would not be necessary.
