Please follow the general troubleshooting steps first:

• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [ ] Confirmed this is a problem with specific formulae and not Homebrew/brew? If it's a general Homebrew/brew problem please file this issue at https://github.com/Homebrew/brew/issues/new

Bug reports:

So I found this issue when I tried to run gem update but I got this message:
/Users/OMMHOA/.rbenv/shims/gem: line 21: /usr/local/Cellar/rbenv/0.4.0/libexec/rbenv: No such file or directory
Message for ruby -v or ruby --version:
/Users/OMMHOA/.rbenv/shims/ruby: line 21: /usr/local/Cellar/rbenv/0.4.0/libexec/rbenv: No such file or directory
I checked that lib and there was only usr/local/Cellar/rbenv/1.1.0/...

After
brew update
brew upgrade
brew uninstall rbenv
brew uninstall ruby
brew uninstall ruby-build
brew install rbenv
brew install ruby

Same error message and there was no rbenv dir under /usr/local/Cellar/

After brew install ruby-build same thing.

So brew install rbenv installed the 1.1.0 for me again which resulted in the same error message. The only way to make everything work was getting rbenv 0.4.0 from here and putting it into /usr/local/Cellar/rbenv by hand.

After manually putting in 0.4.0:
ruby -v:
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin15]

I'm confused what's the problem? I tried reproducing the same errors and I have no luck.

You perhaps need to run rbenv rehash. Regardless this doesn't seem to be a Homebrew issue but an rbenv one.
