Doctor doesn't find ruby-build after Debian-based install

[lofidevops]

Steps to reproduce:

• sudo apt install rbenv (install rbenv)
• ruby-build --version (confirm ruby-build also installed)
• which ruby-build (confirm ruby-build location)
• Run rbenv-doctor

What should happen:

• ruby-build returns version & location
• Doctor results all "OK", including ruby-build

What happens instead:

• ruby-build returns version 20170726
• which ruby-build returns /usr/bin/ruby-build
• Doctor returns:

Checking for `rbenv' in PATH: /usr/bin/rbenv
Checking for rbenv shims in PATH: OK
Checking `rbenv install' support: not found
Unless to plan to add Ruby versions manually, you should install ruby-build.
Please refer to https://github.com/rbenv/ruby-build#installation

Counting installed Ruby versions: none
  There aren't any Ruby versions installed under `/home/user/.rbenv/versions'.
  You can install Ruby versions like so: rbenv install 2.2.4
Checking RubyGems settings: OK
Auditing installed plugins: OK

Notes:

Operating system: PureOS 8 (~= Debian testing)

$ which rbenv                                                                                                                                                       
/usr/bin/rbenv
$ rbenv --version                                                                                                                                                   
rbenv 1.1.1

However, the following commands work:

• rbenv install -l
• rbenv install 2.4.1

Thank you for reporting! That is interesting. Are you able to locate where rbenv-install executable was placed by debian packages?

/usr/bin/rbenv points to /usr/lib/rbenv/libexec/rbenv

And rbenv-install is amongst other files in /usr/lib/rbenv/libexec...

@kwill Thanks for looking that up! Perhaps we should amend rbenv-doctor to include the location of {rbenv-install-location}/libexec/ when searching for rbenv-install. PR welcome!
