Well I am sorry to waste your time but it appears I have 2 versions of
gnu common c++ that I had compiled and installed. One of them was
linked to the old libstdc++3 so I am just going to have to remove them
and recompile a few things. At least I know wtf is going on now and
maybe I can use gdb now ;). Once again, sorry for wasting your time.

realists'' say that profit is the only ideal...just ignore them, and use
copyleft all the same.
