upgrading slink cripples dselect/apt (and X) !!!

[Zack Brown <zbrown@lynx.neu.edu>]

Help!

I upgraded some packages this morning, and now running dselect gives the
following error:

dselect: error in loading shared libraries
/usr/lib/libstdc++-libc6.0-1.so.2: undefined symbol: __register_frame_info

Also, X gives graphics screen and mouse cursor, then craps out, giving the
same error in ~/.xsession-errors

I tried using dpkg to install the old packages, but it either refuses to
uninstall libstdc++ because so many packages depend upon it, or to install
the old version because a version is already installed. Catch 22.
