Great!  I added a copyright line for you, fixed up indentation (see the
bit in the manual for how to do that automatically), and added a
comment—patch attached.

It built for me, but then I realized I had missed something: the
external/ sub-directory contains lots of bundled copies of external
tools, and indeed, the ‘configure’ phase shows:

Some of these are already packaged, so it should be a matter of adding
them to ‘inputs’.  For the remaining ones, it would be extra packaging
work to do.

The goal is to address all of these, but if we can address the majority
of these, perhaps we can commit a first version of the package with a
FIXME stating what remains to be done, if you prefer.

Thanks, and apologies for overlooking it before!

Ludo’.
