Newt and Guix pull failing

[brettg]

Hey all,

I reference the newt module in this file of my channel
https://git.sr.ht/~brettgilio/guix-system/tree/master/guile-modules/gscale/screen.scm

However, when I `guix pull` it fails to build citing that there is no 
code available for that module. I have guile-newt installed system wide, 
and to my local profile manifest, but neither of those fix the issue.
