Some of these languages (ponyc) are still...prototypes. Yeah you can get them working for a limited set of "working" and with very specific setup->configurations. If every language included a Docker or VM with it already set up for some level of demo, I think a rate for adoption/learning them would uptick.
As to the ease of compiling it... I've always compiled it from source, to track some bleeding-edge features, and compiling ponyc is a breeze.
