There are a couple of things going on here.  Calling the Guix APIs from
Guile will use the 'system-installed' Guix, unless you have fiddled with
GUILE_LOAD_PATH.

You can use 'guix repl' to use the _current_ Guix instead (the one
obtained with 'guix pull'), where this problem has been fixed.

The system-installed Guix in turn fails because of a bug that was fixed
in 179e6c524ae4957e6ace83f72a5651767f786ca4, and ultimately
977f478090fd96e73463efb67c56fb32f28828bd which updates the 'guix'
package to include the fix.  If you reconfigure on a recent Guix, the
missing patch error should go away.

Hope this helps!
