Thanks for this explanation.  It reassures me that there's nothing I've 
broken here!

In this particular case, it appears that the conflicting dependencies -- 
on openldap-client and openldap-sasl-client -- have arisen as something 
of a side-effect of the package installation process, since net/ceph 
(which is what I'm trying to install) doesn't declare a dependency on 
either of them, and building net/ceph the old-fashioned way, within 
/usr/ports, works fine.  I'm not quite sure what this is telling me.

However at this point I'm not _completely_ sure of the sequence of 
operations which have taken me where I am now, so I'm not positive I'd 
be able to reproduce things.  So I'm going to step quietly away from the 
machine (unless anyone thinks this is interestingly anomalous).

Best wishes,

Norman
