I can reproduce this with the test code being `(group-information "root")`.
FWIW, I get a warning during compilation, not an error. The compiled
code runs just fine and emits the expected result. This is due to the
relevant entry in the `types.db` file stating that the group-information
procedure accepts an integer only. If you unpack the release tarball
and change the enclosed `types.db` to specify `(or string fixnum)` for
the first argument of the function, the compiled CHICKEN should behave

Have you inspected the documentation of that procedure? It accepts
three arguments, the path to the file and the new user ID and group ID,
therefore it allows implementing both `chown` and `chgrp`. I don't
think an extra procedure is necessary.
