I installed Octave 3.8.0 from here:
Ok. That is an experimental build. I don’t think it was intended for Yosemite. But it is good news that it runs.
I am not savvy enough to "build" anything myself. :) I have no idea what gfortran is either and have no idea if I even have it much less where it came from…
The gfortran came bundled with Octave. Although Octave works on Yosemite, gfortran does not. I expect that is because it relies upon some libraries that changed.
I guess part of the problem could be that there is no installer for OSX Yosemite yet so I grabbed the 3.8.0 version for OSX 10.9.1. It seems to *mostly* work. Maybe this is the reason I can't install packages though...?

If you need to install packages, I recommend you first uninstall Octave. From the Finder -> Go -> Go to Folder and enter /usr/local. Then single click on the octave folder and Finder -> File -> Move to Trash. You’ll need to enter your password to do that. Be careful not do delete anything else.
Once Octave is gone, you can install Octave via Fink.
There are some simple instructions at this link …
If you have any trouble with the instructions, let me know and I can fix them.
