I suggest leaving packaging this for later.

I assume we are talking about this package here:
https://github.com/Anaconda-Platform/anaconda-project

> (define-module (gnu packages Anaconda)

I believe we already have a module where this would fit, so please
look around in gnu/packages for filenames where you could add this.

There is no such build system, most probably you will need
python-build-system here.

I don't think you will need gawk here...

I believe 'anaconda' would be better.

Also here.

Most probably you should fetch from some python package repository.

Also python-build-system here.

These well need adjustment, as needed for the given package.

With all that said, what I recommend is to try either:

1. use guix import to get the metadata for this package, if it is
available in pypi.
2. use guix import to generate a definition for some package from the
cran repository instead. (These are easy to package, the importer does
most of the job).

I would try #2 first, as it is a good way to get a contribution fast.
