I installed `password-store' and simple invocation failed:

  $ LC_ALL=C pass
  Password Store
  /home/tcech/.guix-profile/bin/pass: line 324: tree: command not found

After manually installing `tree' package it works as expected.

A `pass' is bash script, shouldn't be inputs be changed to propagated-inputs?
    (inputs `(("gnupg" ,gnupg)
              ("pwgen" ,pwgen)
              ("xclip" ,xclip)
              ("git" ,git)
              ("tree" ,tree)
              ("which" ,which)))

Best regards,
