The license text appears to be missing, even though the Expat license
says:

  [...] subject to the following conditions:

  included in all copies or substantial portions of the Software.

So as-is, I don't think we can include r-unpivotr in Guix.  Would
probably be easily resolved with a PR or issue at
<https://github.com/nacnudus/unpivotr>.
