Open GL and FLTK dependencies

[Merzong]

Dear everyone,

I’ve just started using Octave (installed via Homebrew on OS X 10.10.5) for my 
research.

First, I attempted to load a script file my predecessor gave me, but failed 
with an error “__fltk_uigetfile__: not available without OpenGL and FLTK 
libraries”.
I googled about the dependency and tried doing “brew install fltk”, “brew 
install glfw2” and “brew install glfw3”, but still get the same error.

Would anyone know the solution to this problem?

Thanks in advance,
Merzong
