Pete, thank you for the useful information. I have followed the instructions 
in 
http://www.riverbankcomputing.co.uk/static/Docs/QScintilla2/index.html
and the process worked without error messages.  Sorry for the noise!

Thank you for the advice - greatly appreciated.  I will certainly give it 
careful thought in my future endeavours.  OTOH, it is tempting on occasions to 
take the lazy alternative - when  your age is approaching 90  (3 years and 8 
months to go   :).

Great to see you active and still serving SUSE community.  Tempting to return 
to it, but ubuntu is nice and easy...

Many thanks again,

Al.
