It might also be useful for the error message to differentiate the two possibilities that users might interpret or act on differently:

1. a necessary package is not installed at all, install it

2. a necessary package is installed, but the version is not new enough, it needs to be upgraded

The pkg function prints the following error message when the user installs a package that depends on another package that is not yet installed (or is too old)

error: the following dependencies were unsatisfied:
   parallel needs struct >= 1.0.12

This error message could use some small tweaking, without making it too much longer, to help users that are unfamiliar with the 'pkg' command or the Octave Forge packages in general.

For example, maybe something like this?

error: the following packages are missing, please install them with "pkg install -forge"
    parallel depends on struct (>= 1.0.12)

Of course, a package dependency may not be installable with "-forge", so that advice is not completely honest.

Other ideas?

Motivated by feedback on https://lists.gnu.org/archive/html/help-octave/2019-05/msg00120.html
