This is why we also give ourselves the ability to fall back to the safe 
position of having all of the dependencies installed in a private 
directory.  In most cases it won't be an issue because we control the 
software (NSPR, NSS, mozldap) or the software isn't that critical 
(netsnmp, icu).  The two exceptions are bdb and cyrus sasl.  For bdb, it 
will be absolutely critical to the operation of the server to use the 
exact supported version, no more, no less.  For the near future, this 
means 4.2.52 + the recommended patch set, which is what is provided with 
the latest db4-4.2 packages on RHEL/Fedora Core.  Something similar 
applies for cyrus-sasl and kerberos.  The RPM will reflect this in its 
Requires.

Slowly.  We're slowly working our way up the stack.  Next on the hit 
list is Admin Server.
