Thanks for the information. 

I switched to my guix on parabola and cloned first yours and them my repo.

Then I imported minimatch again to make sure the hash is right and it worked!

Status:

I now got these working 95 % built with guix:
* tap
* grunt
* coffee-script
* @babel/core and /cli

In total these have 300 dependencies that now work.

I got stuck with tape because one of the dependencies need typescript to build 
and typescript depends on gulp.

Gulp is a nightmare (304 dep with multiple circles if versions are not 
considered).

If I disable building on this one dependency tape would probably work.
