Upgrading to gnome 2.26 problem

Hi,

I have some problems running gnome-session 2.26 on freebsd8. It appears
that dbus is missing a required library and so makes gnome-session
unusable. I also have some difficulties building hal, and thought it
might be related. Plus, it was running fine on 2.24. Problems started
when upgrading with portupgrade gnome to 2.26. So I was thinking that perhaps
i need to make another buildworld since it might depends on recent libusb
changes, but I'm just guessing. Would there be an alternative or quick fix
for avoiding the buildworld/installworld step or is there something in -CURRENT
that is required for upgrading fully to gnome 2.26 ?



Thanks in advance for your help,

erob
