No, all done by hand, I never used CKAN.
I got the zip file for Spectra fresh from Spacedock. Spectra-v1.1.7.zip, 393,393,540 bytes, MD5=c585a28bb6fd4b3a540f4d5d0200efc7
Your .url files don't work on Debian/Gnome3. So I opened them in a text editor, copied the URLs into my browser and used the download links there. Unzipped all the stuff and followed your instructions step for step.
Thanks for your work on this project!
