This looks like you are creating a starter-script which is pointing to
the source. This will not work, since the source will not be installed
when installing the package.

You want to

- copy the source file into (string-append out "/share/" ,name)

- create a starter script

I also suggest using a shell-script as starter (instead of a guile
wrapper), since this is more natural for me.
