meld-1.1.5.1_1 issue

[Steve Franks]

I've been around the bend for several weeks beating this thing.  This
can't just be a problem on my vanilla system.

First, the preliminaries:

    FreeBSD dystant.dyndns.biz 7.0-STABLE FreeBSD 7.0-STABLE #1: Mon
May 12 14:09:43 MST 2008
root at dystant.dyndns.biz:/usr/obj/usr/src/sys/DYSTANT  amd64
    meld-1.1.5.1_1      GNOME 2 visual diff and merge tool
    python25-2.5.2_1    An interpreted object-oriented programming language
    py25-gnome-2.22.1   A set of Python bindings for GNOME 2
    py25-gtk-2.12.1     A set of Python bindings for GTK+
    gconf2-2.20.1       A configuration database system for GNOME

Now, the error:

    [steve at dystant]$ meld
    Traceback (most recent call last):
      File "/usr/local/bin/meld", line 93, in <module>
        import meldapp
      File "/usr/local/lib/meld/meldapp.py", line 28, in <module>
        import prefs
      File "/usr/local/lib/meld/prefs.py", line 52, in <module>
        import gconf
    ImportError:
/usr/local/lib/python2.5/site-packages/gtk-2.0/gconf.so: Undefined
symbol "g_assertion_message_expr"

What I tried:

    sudo portupgrade -Rf meld

*note* the -f option...that took awhile and did no good...
