[help request] Librespot/Spotify Connect on Pogoplug Pro (1 reply)

I'm interested in adding Spotify Connect functionality to my Pogoplug. For those who are not familiar, Spotify Connect allows your device (the pogo in this case) to show up as a remote speaker from within the Spotify App (on your computer or phone). You can play anything in the Spotify ecosystem to your Spotify Connect device and the audio gets pulled directly from Spotify servers. So you could shut your device off, go out of range, etc and the music keeps on playing.

I'm most interested in running this fork of Librespot which includes Metadata Pipe support. Buy outputting the audio and metadata from Librespot to a pipe, a program I'm running called Forked-Daapd can pick that up automatically and stream the tunes to any of my Airplay/Shairport-sync wireless speakers. The metadata would then populate the web interface for Forked-daapd or the Apple Remote app, allowing for easy volume control and nice cover art/titles/etc.

The problem is, Librespot requires Rust to be installed in order to build. When I try installing Rust I get the following:

curl https://sh.rustup.rs -sSf | sh
info: downloading installer
Illegal instruction

Any advice on next steps I can take to troubleshoot the installation would be much appreciated. I'd love to convert this help request into a how-to in the future :)
