Re: [ruby-gnome2-devel-en] segmentation fault from require 'gtk2'

[Rob T. <rtr...@gm...>]

Hmm, you may be onto something. I've tried a lot of things, but one thing I
tried was this:

sudo brew uninstall gtk
sudo brew install gtk+

I also (separately) tried installing rb-gnome from macports with

sudo port install rb-gnome

...and I got a little farther, but now my little test script is failing
with:

$ ruby ~/test.rb

I'm guessing that libfreetype 18.0.0 was installed as part of macports.
I'll try updating macports and seeing if I can get a newer version of
freetype.
