Unfortunately, Mojave:
ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin18]

So I install ruby 2.7.7

grrr... it's still trying to use /usr/bin/ruby

but

> root at mac:~$ /opt/local/bin/ruby -S gem install coltrane

installed it.

idky my ruby $PATH seems stuck on /usr/bin/ruby, but thanks to your tip, I was able to  install coltrane, and it seems to be working. Neato CLI music utility.

Thank you, Austin!
