ldconfig responds with Illegal Instruction, cannot

[Chris Purves]

A recent upgrade with aptitude on testing exited halfway through with the following error:

Preconfiguring packages ...
Setting up libpam0g (0.76-23) ...
/var/lib/dpkg/info/libpam0g.postinst: line 3: 31771 Illegal instruction     ldconfig
dpkg: error processing libpam0g (--configure):
 subprocess post-installation script returned error exit status 132
Errors were encountered while processing:
 libpam0g
E: Sub-process /usr/bin/dpkg returned an error code (1)

In addition I cannot use dpkg-reconfigure for many packages due to ldconfig not working.

I have found others with the same problem, but reported over a year ago.  I downloaded libc6 and installed with dpkg -i but that didn't fix the problem.  It's been like this for about three or four days and still no bug report in libc6, so I assume that the problem is not common.

I'd appreciate any help.  Thanks.
