Is there an active firewall on the machines?  It looks like the connect

node that just checked in.

Did you download a tarball or did you use svn to grab the latest code?
If you downloaded a tarball missing configure please let us know which
one is broken.  Everything looks fine with the tarballs for rc1 as well
as the nightly tarballs for 1.8 and trunk.
