Where should libslapd.so go?  The reason it works is because libtool 
links ns-slapd against libslapd.so using rpath.  I'm not sure why, and 
the Fedora folks generally frown upon the use of rpath.  So if someone 
makes us take out the rpath, we'll either
1) have to move libslapd.so to one of the system lib paths
2) continue to use a script that sets LD_LIBRARY_PATH
3) use ldconfig to add $_libdir/fedora-ds to the default ld.so path

The other nice thing about having a script is that it gives us the 
ability to insulate ourselves from incompatible changes on the operating 
system.  Let's say that for some reason the system is upgraded to a 
version of libdb4 that we know has problems with DS, but must be used 
for other applications on the system.  If we use the shell script, this 
gives us the ability to drop in our own private version of libdb into 
$libdir/fedora-ds without either interfering with the system directory 
or adding $libdir/fedora-ds to the ld.so default path, both of which 
could interfere with the other applications on the system that cannot 
use our private libdb.

We still need the scripts on RHEL4, Solaris, and HPUX, unless we do some 
tricks with rpath.
