Basic clutter example program fails in clutter_init(); is the clutter port working for anyone?

I am just trying to show myself that it works by running one of the example programs that come with Clutter. I've boiled it down to a pretty minimal example that just calls clutter_init(), the first call of any Clutter program.

At least I can reproduce the problem with the same versions. Note that
clutter can give you more debug output using the right arguments:

$ ./clutter --clutter-debug=backend

I also added the following lines to the Portfile to run the included
test-suite with 'sudo port -vo test clutter':

test.run    yes
test.dir    ${worksrcpath}/tests/conform
test.env    CLUTTER_DEBUG=backend

This fails early on a first test involving XOpenDisplay():
