GLIBCPP_3.2 not defined

[curt brune <curt@acm.org>]

Hi,

I just did "apt-get update; apt-get upgrade" for SID and am getting
all sorts of errors.  I upgraded about a week ago with any problems.
Here's an example from the emacs21 package:


Preparing to replace emacs21 21.2-6 (using .../emacs21_21.3-1_i386.deb) ...
Unpacking replacement emacs21 ...

dpkg: error while cleaning up:
 subprocess post-removal script returned error exit status 127

Several other packages complain in exactly the same way -- something
about "GLIBCPP_3.2 not defined" occurring in "update-menus".

I've never seen this before.  I did a little research and saw this
from the mailing lists in January :
http://lists.debian.org/debian-boot/2003/debian-boot-200301/msg00393.html

This message talks about mklibs.py, but I do really understand what is
going wrong.  Any clues?

Cheers,
Curt
