Gnome-Panel fails to upgrade

[Sean Cavanaugh]

?I am unable to upgrade /x11/gnome-panel. every time i run portupgrade -a, i 
fails with the following line while compiling

-----------------------------------------------------------------------------------
g-ir-scanner: warning: Option --strip-prefix has been deprecated;
see --identifier-prefix and --symbol-prefix.
Couldn't find include 'GConf-2.0.gir' (search path: ['.', 
'/usr/local/share/gir-1.0', '/usr/share/gir-1.0', 
'/usr/local/share/gir-1.0'])
gmake[3]: *** [PanelApplet-3.0.gir] Error 1
gmake[3]: Leaving directory 
`/usr/ports/x11/gnome-panel/work/gnome-panel-2.32.1/libpanel-applet'
------------------------------------------------------------------------------------

this obviously has the bad effect of blocking 21 other ports from getting 
updated (aka, the rest of gnome)

anyone have any clue of what needs to be done to fix this issue?
