Rob,

Thank you for responding.

While the issue is known, the workarounds are a little above my head. 
People suggest, for example, to use a shorter key length 
((`cl_sortkey`(78)), but I have no idea where to implement that.

Another person says "Changed table definition in CVS HEAD for 1.5; 
cl_sortkey is now limited to 86 characters". Again, I have no idea how 
to make this change.

Is there a slightly more verbose description available about how to do 
these things?
