Hi.
There are currently two conflicting definitions of ocl-icd in
"opencl.scm":

--8<---------------cut here---------------start------------->8---
(define-public ocl-icd
  (deprecated-package "ocl-icd" opencl-icd-loader))
--8<---------------cut here---------------end--------------->8---

and

--8<---------------cut here---------------start------------->8---
(define-public ocl-icd
  (package
    (name "ocl-icd")
    (version "2.3.2")
    (source
     (origin
       (method git-fetch)
       (uri (git-reference
             (url "https://github.com/OCL-dev/ocl-icd")
             (commit (string-append "v" version))))
       (file-name (git-file-name name version))

    (description
     "This package provides an OpenCL @acronym{ICD, Installable Client Driver}
