Your source tarball contains multiple gzipped files, one of which 
itself a tarball:

Guix's heuristic is very simple: chdir to the first (or last, 
dunno) file it finds in a tarball, because foo-1.2.3.tar.gz is 
expected to contain a single foo-1.2.3 directory.  It usually 
works, but here it fails, so you need to use url-fetch/tarball 
and/or further unpack the double-packed sources yourself in a 
custom phase.

Kind regards,
