This is happening because modules of your channel depends on Guile-Newt,
and Guile-Newt is missing, so ‘guix pull’ fails to build your channel
modules.

How would ‘guix pull’ know that your channel depends on Guile-Newt?  It
cannot guess it, and currently there’s no way to express such a
dependency.

Does that make sense?

Also note that a channel is meant to provide packages or services, so it
is surprising to have a channel depend on Guile-Newt.
