yes, this now seems to be integrated into the src.tgz bundle - I found
this after I'd done some poking around in my local tree.
The problem I'm having is that I don't seem to be able to build with the
following arguments:
sh ./build.sh -x release
as the build process complains about missing source in a directory
(which from memory is either 'external' or 'extsrc', I can't recall ...
I don't have access to my host to confirm this at the moment) ... this
is what led me to suspect I was missing a source set, as has happened in
the past ...
