I appreciate the theory that /etc/cron.d/koha (as I quoted it above) 
should|could|would pick up the variables KOHA_CONF, KOHAPATH and PERL5LIB

In fact I think this worked for Koha 3.6.7 on Ubuntu 12.04 *i386* (from my 
notes, no errors; but that install has been trashed) -- but it does NOT 
work on either of our two 64 bit servers  -- hence the need to add the 
'export' lines to /home/koha.bashrc and make them available *before* the 
cron job is called.

I have not had time to find out *why* the 32- and 64-bit builds possibly 
differ and satisfy my curiosity. All I've done is come up with a working 
solution and share it with this community -- with the caveat that YMMV and 
there might well be other [more elegant?] ways around it.

Best - Paul
