Does the slang-devel package need ldconfig in %post? Removing it breaks anything
that depends on non-devel slang until I ldconfig manually.

How reproducible:

/usr/lib# ls -oh libslang* 
-rw-r--r-- 1 root 929K Feb 12  2006 libslang.a
lrwxrwxrwx 1 root   17 Aug 22 07:07 libslang.so -> libslang.so.2.0.5
lrwxrwxrwx 1 root   17 Aug 22 07:07 libslang.so.2 -> libslang.so.2.0.5
-rwxr-xr-x 1 root 704K Feb 12  2006 libslang.so.2.0.5
lrwxrwxrwx 1 root   10 Aug 22 07:07 libslang-utf8.a -> libslang.a
lrwxrwxrwx 1 root   17 Aug 22 07:07 libslang-utf8.so -> libslang.so.2.0.5
/usr/lib# rpm -e slang-devel
/usr/lib# ls -oh libslang*   
-rwxr-xr-x 1 root 704K Feb 12  2006 libslang.so.2.0.5
/usr/lib# mc  
/usr/bin/mc: error while loading shared libraries: libslang.so.2: cannot open
shared object file: No such file or directory
/usr/lib# ldconfig 
/usr/lib# mc

Finally, it works again.
