rbenv, et al are having issues with Arch and ruby. I'm not sure where
the source of the issue is but I've tried a couple of different install
paths for both ruby and the version management tools. They all seem to
be having about the same issue.
To use one or the other specify set variable to either `doom` or
`spacemacs`. If no value is specified it will default to Spacemacs,
though this may change in the future.
