This line creates a new named environment "xl" in spack's default location, but the next line activates a directory-based environment at ${SPACK_ENV} (/opt/spack-environment/xl). These are two different environments. The directory already contains a spack.yaml file (copied at line 44), so it can be activated directly without creating a new environment. Other similar usages in this file (lines 178, 283, 322) activate the directory environment without calling 'spack env create' first. This line should be removed.
