Error Compiling telepathy-mission-control-5.14.1

About halfway through emerging gnome3, now, and get a failure
compiling telepathy-mission-control.

The build log is at: http://pastebin.com/032vEEpc

It looks like the first part of the error is:

/usr/bin/python ../tools/glib-ginterface-gen.py \
        --filename=_gen/svc-Account_Interface_Hidden \
        --signal-marshal-prefix=_mcd_ext \

        --include='"_gen/signals-marshal.h"' \
        --not-implemented-func='tp_dbus_g_method_return_not_implemented' \
        --allow-unstable \

How to fix a syntax error during a compile?
