If 'install-file' works here then the above 6 lines can be 2, something
like:
(install-file (string-append source "/screenfetch.1")
              (string-append %output "/man/man1/"))

you can use the patch-shebang function here, should help a bit.

Ideally these should wrap the binary rather than being propagated.
