I think it's a bug in the "various.lisp" file. Inside it there is:

--8<---------------cut here---------------start------------->8---
(declaim (type double-float PII PI5))

(defconstant PII (the double-float #.(* PI 2d0)))
(defconstant PI5 (the double-float #.(* PI 0.5d0)))
--8<---------------cut here---------------end--------------->8---

However the Common Lisp spec indicates that 'pi' is a 'long-float'. It
works with SBCL because it implements 'double-float' and 'long-float' as
the same type (which is allowed according to the spec). However in ECL
the types are different ('long-float' has more precision than
'double-float').

Converting 'pi' to a 'double-float' should make the code work in both
SBCL and ECL (note: I've not tested):

--8<---------------cut here---------------start------------->8---
(declaim (type double-float PII PI5))

(defconstant PII (the double-float #.(* (float PI 1.0d0) 2d0)))
(defconstant PI5 (the double-float #.(* (float PI 1.0d0) 0.5d0)))
--8<---------------cut here---------------end--------------->8---

Hi Guix team!

Preparation list of patches for art generation system Weir
I've packed it but it's failed on ECL build with

DOUBLE-FLOAT
