make clean-go breaks my build environment

[jgart]

hi,

after running `make clean-go` the build gets consistently stuck on
this message:

WARNING: Use of `load' in declarative module (guix ui).  Add #:declarative? #f 
to your define-module invocation.
WARNING: (guix build python-build-system): imported module (guix build utils) 
overrides core binding `delete'

am i missing a step?

all best,

jgart
