I would consider myself a casual builder of Emacs. :-) On one 
machine, I compile and install Emacs from source. Not to stay up 
to date with development but just to have the latest Emacs 
release. (When I first installed that machine, there were no 
pre-built packages of a recent Emacs available.)

And yes, I think if I'd run into this problem, I'd appreciate the 
extra information. I mean, of course I would google "Cairo" and 
"HarfBuzz", but knowing what I'm looking for would make fixing the 
problem easier.

Just my €0.02.
