GTK2_RC_FILE and ~/.gtkrc-2.0 ignored

[Kevin Layer]

I've googled and googled and tried a bunch of things, but I can't get
GTK2 installed via macports to use any theme.  I did this

  # port install gtk-theme-switch gnome-themes

and I even downloaded themes from here

  http://art.gnome.org/themes/gtk2 

and changed my ~/.gtkrc-2.0 file and GTK2_RC_FILE env variable to
point directly to the gtkrc in the theme, but nothing works.  The
buttons and everything else in the app looks the same before and after
all this work.

Anyone have ideas I can try?   Thanks.
