languages: flag missing dependency requirement (#194)
This is in part designed to handle situations described in https://github.com/Homebrew/legacy-homebrew/issues/42273
where we tell someone to install a special dependency, but because we (rightly, IMO)
resolve special dependencies first users can end up being told to execute a command
on a tool that isn't yet installed and isn't immediately obvious how to install it.
In the situation raised there, with the `sile` formula people are being told to
`luarocks install xyz` but we hadn't installed Lua for them first, so they just
get a `command not found: luarocks` message. Perhaps it should be obvious enough
how to install said tools by looking at the formula's dependencies,
but it's not a huge burden on us to make life easier than that.
Shuffled over from https://github.com/Homebrew/legacy-homebrew/pull/42576.
