thanks.
there have been large changes (patches of several thousand lines)
lately. we know that currently the trunk is just "unstable".
due to other things going on we might not be able to fix it
as timely as we would like. should be working end of next week again.
you may check frequently before that, though, in case we found time to
get it going again earlier.  sorry for that.

make sure your kernel has "CONFIG_CONNECTOR" enabled.
that might help already.
