Can´t install Gems

First of all I have no more than thanks and nice words to all the people pushing this web, teaching courses and helping in the forum. So as I am new on ruby and in programming in general I took the Ruby Foundations course, everything works fine and I learned some basics, then I start this rails course and the way you recommended for installations changes and I´m completly stack now... can´t install gems. I searched in the forum and the web to try to fix this without success. I tried so many things that now I´m lost, I deleted and re installed xcode a few times. I have tried what says in here https://teamtreehouse.com/forum/following-the-installation-of-osxgccinstaller-i-cannot-install-gems-basically-use-ruby-in-programming but still not working and looks like getting worse

Please somebody help me :D I´m running a Mac with OS 10.9.5, in the first course I had installed rmv,homebrew, git and ruby, then in other course said to install GCC, what gives me conflicts with homebrew as many of you know... when i run brew doctor terminal returns the following: 

Warning: You have an outdated version of /usr/bin/install_name_tool installed.
This will cause binary package installations to fail.
This can happen if you install osx-gcc-installer or RailsInstaller.
To restore it, you must reinstall OS X or restore the binary from
the OS packages.

Warning: You seem to have osx-gcc-installer installed.
Homebrew doesn't support osx-gcc-installer. It causes many builds to fail and
is an unlicensed distribution of really old Xcode files.
Please run `xcode-select --install` to install the CLT.

now everytime I open the terminal this appears

-bash: rbenv: command not found
-bash: rbenv: command not found
-bash: rbenv: command not found

when I write the line git clone https://github.com/sstephenson/rbenv.git ~/.rbenv terminal returns the following: 

fatal: destination path '/Users/Tacito/.rbenv' already exists and is not an empty directory.

when I try to install gems like this

gem install bundler terminal returns the following: 

-bash: /usr/local/bin/gem: @@HOMEBREW_CELLAR@@/ruby/2.1.5/bin/ruby: bad interpreter: No such file or directory

so hope somebody can guide me cause I really want to learn how ruby on rails works

homebrew seems to want to use xcode command line tools:

Please run `xcode-select --install` to install the CLT.

you cant install the CLT using that command anymore, however you can download them from the developer center after creating a free account.

download the Xcode CLT here

Thanks for the answer Stone! I did what you said and restart the computer and still have the same message when i run brew doctor...strange... I think i tried so many things that now my mac and me are a mess Thanks anyway but for me the most important thing is to be able to install rails and gems You think i have to re install the OS or could be an easier solutions for this problems?

Judging from the instructions in the error message you posted, you'll need to reinstall OS X from the Mac App Store, then install all the necessary command line tools that previous courses had you install, but be sure not to install osx-gcc-installer

Id say this is probably your last resort. Id spend a bit more time searching for a solution before completely reinstalling.

there is definitely an easier way to fix this

try uninstalling the xcode CLT, then installing the CLT again 

sudo /Library/Developer/4.1/uninstall-devtools -mode=all

Thanks a lot for you time guys, but it looks like is not working, very strange... I have installed again the CLT and was successful, but still have the message when I check the Brew doctor. And when i try to uninstall the CLT with the line

sudo /Library/Developer/4.1/uninstall-devtools -mode=all

terminal returns

sudo: /Library/Developer/4.1/uninstall-devtools: command not found
