Hi Reinhard,

You can debug the kpathsea in texlua just like you would a standalone
script by setting KPATHSEA_DEBUG=-1 in the environment before running
the script, perhaps that will help.

Also, have you tried

      kpse.set_program_name('ppower4', 'ppower4')

Or you could try to set the program name to 'kpsewhich' (that is what
I usually do in standalone scripts).

The wrapper luatex provides around kpathsea is really shallow, so
I am just as surprised by this problem as you are.

Best wishes,
