dbus-glib: error rebuilding in rev-upgrade

[adamcrussell (Adam Russell)]

I am doing an upgrade of several ports and am getting this error when it gets to dbus

--->  Building dbus
Error: org.macports.build for port dbus returned: command execution failed
Please see the log file for port dbus for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_dbus/dbus/main.log

    (file "/opt/local/bin/port" line 5254)

dbus/main.log is attached

Any advice on how to get through this? Thanks!
