ack installs, but reports "use: command not found" #47302
Description
Issue description
The ack tool can be installed, but reports errors like "use: command not found". These errors are symptoms of trying to execute a Perl script with Bash; I am not sure why the shebang line in the ack script is not working.
(Also, unrelated: while nix-shell -p ack works, nix-env -i ack instead reports "error: selector 'ack' matches no derivations". Perhaps I have some misunderstanding about what the arguments to these commands mean.)
Steps to reproduce
$ nix-shell --pure -p ack
$ ack --help
