libslang problem after upgrade to potato

[Neil Booth <NeilB@earthling.net>]

After doing a distribution upgrade from slink to potato, I keep
getting errors about /usr/lib/libslang.so not existing.

Doing "ldconfig /usr/lib" results in 

ldconfig: warning: can't open /usr/lib/libslang.so (No such file or
directory), skipping 
ldconfig: warning: can't open /usr/lib/libslang.so (No such file or
directory), skipping

The libslang contents of /usr/lib are as follows:-

lrwxrwxrwx   1 root     root           20 Nov  3 00:31 libslang-ja.so.1 -> libslang-ja.so.1.2.2
-rw-r--r--   1 root     root       242144 Jun  1 04:37 libslang-ja.so.1.2.2
-rw-r--r--   1 root     root       335618 Aug 13 13:20 libslang.a
lrwxrwxrwx   1 root     root           22 Aug 13 13:23 libslang.so -> /lib/libslang.so.1.2.2

The problem is that I have a dangling symlink here.

1) Should I have an English libslang here?  Or should I delete the symlink?
2) I have one in /lib as so

lrwxrwxrwx   1 root     root           17 Nov  2 23:57 libslang.so.1 -> libslang.so.1.3.9
-rw-r--r--   1 root     root       328428 Oct 14 08:59 libslang.so.1.3.9

Should this be here?  Should it be in /usr/lib instead, or symlinked
from there?

If I try an "apt-get install slang1" it tells me I already have the
newest version, so I'm not quite sure where to go from here.  I
daren't reboot without sorting this out as libslang is in the base
distribution, and quite a few upgrades did not go smoothly because of
this libslang problem.

Any advice appreciated.

Neil.
