The original issue was, that you weren't splitting your arguments
correctly.  (list "argument with spaces") counts as a single argument,
not three.  After adjusting that, I encountered some additional errors
coming from the build system/missing inputs and fixed those up as well,
getting the package into a state in which it at least builds and tests.

You're welcome.  I've attached a patch, that contains my fixes, which
should apply cleanly to guix master.  It mostly follows Guix coding
standards, but it noticeably falls short in the description.  I haven't
found anything, that's useful.  Is there a way of describing this
package in terms of its features?

That's a nice domain to have reserved ;)
