mpdpopm is distributed in a number of formats. The
prerequisites depend on the distribution format, but in any event you
need to have MPD installed & running in order to use
mpdpopm. See also Setting-up mpd.
The pre-built binary distribution, the Debian package, and the Arch binary package require no other pre-requisites.
Downloading mpdpopm from crates.io requires the Rust toolchain.
Building from source via the Autotools distribution further requires the Gnu Autools.
