I did a reply to all so both you and the list were on the email. I
always do a reply to all. It is my understanding that mailman makes
sure that you only get one copy of the email. Did I do something
wrong.

OK I think we had a misunderstanding. I had clutter-trunk built from
jhbuild. I discovered why I had the error. I did not have
gobject-introspection built when I built clutter-trunk. Building
gobject-introspection and subsequently rebuilding clutter-trunk solves
the problem I ran into.
Another issue I ran into is that I run ubuntu and ubuntu does not have
libmozjs in ld.so.conf search path. Simply pasting the following in my
normal .jhbuildrc
#######################
#
# For Ubuntu Intrepid, libmozjs lives in /usr/lib/xulrunner-<version>
# However, that path isn't in ld.so.conf, meaning that it's basically
# impossible to use the xulrunner .pc files and libraries. Work around
# this by deriving the path and adding it to LD_LIBRARY_PATH ourself.
#
import re
import subprocess
_pkgconfig = subprocess.Popen(['pkg-config', '--variable=sdkdir', 'mozilla-js'],
                              stdout=subprocess.PIPE)
_sdkdir = _pkgconfig.communicate()[0].strip()
_pkgconfig.wait()
if _pkgconfig.returncode == 0:
    _libdir = re.sub('-(sdk|devel)', '', _sdkdir)
    if os.path.exists(_libdir + '/libmozjs.so'):
        addpath('LD_LIBRARY_PATH', _libdir)
#########################
solves that problem

Furthermore I replaced metacity-clutter by mutter and have it depend
on clutter-trunk, and clutter-trunk depend on gobject-introspection
and everything works like a charm with normal jhbuild.

These changes are now also in the git repo of jhbuild so it should
work for everyone now when they use normal jhbuild  :-)
