There is a misunderstanding: you can either do 1) OR 2). Actually, approach 2) 
is doing 1) in the particular install directory /Application/Octave.app 
(instead of /usr/local) with many additional steps that are necessary to arrive 
at a nice disk image.

What is the error message exactly? Are we talking about "brew install gnuplot"? 
Maybe you should uninstall homebrew and start from scratch...

As mentioned before, approach 2) can be done independent of 1). If you are an 
experienced command line user and you do not need an app-bundle then approach 
1) is totally sufficient.
