I don't think your problem has anything to do with the base OS.
I think this is only related to the ports tree.

well, the png upgrade was painful for all. But all you need is
to rebuild all png-dependent ports. In your example of gnome-session
you can try to find which port installed it and rebuild that port.
Something like

# which gnome-session

or

# find /usr -name "gnome-session"

should give you the full path to the executable.

Then you can try

# pkg_info -W <full path to the executable>

this should give you the port name. Try to rebuild
it. If all goes well you are likely to be stopped
at another png-dependent port needing rebuilding.
So you just repeat this process for all such ports.

But as I said, if you have lots of png dependent ports
it might be easier to delete all ports and install them
from scratch. I don't use gnome or kde myself, so can't
advise here.
