Development tools cant be found & Configuration Issues

Question

Hello I am trying to install Jekyll and I have scoured the internet for solutions but not made much of a dent. I have the latest version of ruby installed along with homebrew and the developer tools. When in try to install the xcode via "xcode-select --install" I receive the following even though my path is to "/Applications/Xcode.app/Contents/Developer"

xcode-select: Error: unknown command option '--install'.

xcode-select: Report or change the path to the active
              Xcode installation for this machine.

Usage: xcode-select --print-path
           Prints the path of the active Xcode folder
   or: xcode-select --switch <xcode_path>
           Sets the path for the active Xcode folder
   or: xcode-select --version
           Prints the version of xcode-select

When I try to install Jekyll or anything similar I receive:

new-host:~ jameswaltz$ gem install jekyll
