Take a deep breath! You’ll get through this.

  1. Do you have command-line tools installed already? If you type “gcc” in a terminal, what does it say?
  2. Have you installed successfully installed the package inside gfortran-4.9.0-Mavericks.dmg? It should install like any other software, with Apple installer interface.
  3. Once you have done that, type “gfortran” in your terminal: what does it say?
  4. If step #3 fails, can you open the Console, and see if there is anything in there related to why your gfortran installer failed to set things up properly?


PS: the “sudo rm -rf …” line is to *remove* gfortran, not to install it.

You need to read a short intro to the Terminal. It’s not so hard, but you need to learn the basics if you’ve never done it.
You can, for example, see here: http://blog.teamtreehouse.com/introduction-to-the-mac-os-x-command-line

I have never tried Xcode/gfortran integration, but some others have. With the right settings, you can get Xcode to run pretty much any command in its build procedure.
