Hi Christopher,
Gnuastro is still a very young package which is still growing and with
many tools remaining to be included. So unfortunately it doesn't yet
have an ephemeris (positions of objects on the sky) calculation tool.
Thanks to this question, I added a task (link below) in the Gnuastro
project webpage, so it won't be forgotten and it will be included some
time in the future by anyone who is interested.

If you are familiar/comfortable with Python, the astropy library
provides a package for this job, and it is free software:
http://docs.astropy.org/en/stable/coordinates/solarsystem.html
I believe it can be used offline as you wanted, you just need to
download its database (115MB) once. You can write a small Python script
to calculate it using these astropy modules.
I hope this helps :-),
Cheers,
Mohammad
