Ah right, the ‘patch-shebangs’ phase just looks at files in ‘bin’ and
‘sbin’ (see gnu-build-system.scm).
Perhaps you can add a phase somewhere that does along the lines of:
(lambda* (#:key outputs #:allow-other-keys)
(for-each (match-lambda
((_ . dir)
(for-each patch-shebang
(find-files (string-append dir "/share")
".*"))))
outputs)
#t)

Woow, congratulations! :-)
I’m not sure if that would help here, but do you know about
“multiple-output derivations”? It’s used for Libtool for instance: the
‘outputs’ field there means that binaries go into one directory, and the
rest goes into another directory (you see them when typing ‘guix-build
libtool’).
So if there are several kinds of files, you may want to separate them in
different outputs.

Hmm, intriguing. :-)
Thanks!
