I haven't checked if this package is compiled with SPICE support but I doubt it. But it would be nice if the autopackage provided on Celestia's website had the same features as the Windows binary (video capture and DE4xx ephemeris support).
I was wondering since SPICE isn't free software if distributions should package 2 versions of Celestia : celestia-free and celestia-non-free (with SPICE support)?

Note the "publicly available" and "is provided...to the recipient"
I don't know how much clearer they can make it.

If you don't want to use the copy provided with Celestia, you are free to download and use your own copy.

I think I figured out the confusion: there is no 1.5.0 autopackage version of Celestia for Linux, and 1.5.0 is the only version with SPICE and theora support. If you want 1.5.0, you'll have to compile it yourself from the source package. We should address this and build a 1.5.0 autopackage. As for whether that should include SPICE support, I'm not sure: others are better informed on the details of free software licenses.

One other clarification: JPL Ephemeris support is independent of SPICE. There's no option to compile without it, and I just verified that the file jpleph.cpp is in fact in celengine/Makefile.am.
