I would start to transform this way:

    for p in casacore indi libsep libxisf python-asdf \
     python-asdf-astropy python-astrocut python-astropy \
     python-astropy-healpix python-astropy-iers-data python-astroquery \
     python-casacore python-cmocean python-cmyt python-czml3 python-drizzle \
     python-drms python-ephem python-esutil python-extinction python-fitsio \
     python-glfw python-glue-core python-gwcs python-halotools \
     python-lofar-h5plot python-losoto python-mpl-scatter-density \
     python-mpsplines python-ndcube python-pyvo python-rad \
     python-roman-datamodels python-s3path python-sep-pjw python-sgp4 \
     python-sncosmo python-sndata python-soxs python-specreduce \
     python-spherical-geometry python-stsci-stimage python-sunkit-image \
     python-tweakwcs python-viresclient scamp ;
     do
     printf "$p "; ./pre-inst-env guix build -q --no-grafts $p
     done

Just to find the culprit. :-)

I agree that the error message here is quite poor.  Do you have a
minimal example at hand?
