Arch Linux

can't switch to fltk plotting toolkit even though it's installed
steps:
> available_graphics_toolkits
ans =
{
[1,1] = fltk
[1,2] = gnuplot
}

> graphics_toolkit()
ans = gnuplot

> graphics_toolkit("fltk")
error: feval: function `__init_fltk__' not found
error: called from:
error: /usr/share/octave/3.6.3/m/plot/graphics_toolkit.m at line 59, column

> __init_fltk__ % autocompletes, but.. error:
error: `__init_fltk__' undefined near line 7 column 1
> __init_gnuplot__ % autocompletes and executes successfully
