[Gtk-osx-users] could not build libffi

[san hoi <hoisan49 gmail com>]

Hi. I try to build gtk+-3.0.

$ vim ~/.jhbuildrc-custom

moduleset="https://github.com/jralls/gtk-osx-build/raw/master/modulesets-unstable/gtk-osx.modules";

and then,
$ ~/.local/bin/jhbuild build libffi

*** Building libffi *** [1/5]
make
MAKE x86_64-apple-darwin10.4.1 :        0 * all-all
make: *** [all-all] Error 1

Can anyone help me?
Thanks.
