Python package requires fortran compilers

Or alternately, make use of the already-in-the-container mamba with an environment.yml, e.g.

channels:
- conda-forge
dependencies:
- camb

Per build, this may represent a time savings, comparing:

  • run the apt solver
  • download the apt packages
  • install all the app packages
  • solve with pip
  • download the pip packages
  • compile the fortran code

vs:

  • solve with mamba
  • download the conda packages
  • install the conda packages
