Hi Theodoros,

freehdl-config is installed, but it uses a path to pkg-config which is from a 
native-input (so it will not be retained).

Does this ever work again after removing pkg-config from your profile and then 
doing "guix gc" ?  I doubt it...

Same here...

I've pushed PATCH v2 01 to 05 (inclusive) to master as:

- bf6e6c39646e6180f57a5146dd77a3a01d870c9e (adms)
- c5c380100635b47afb11c9bbb213ad1fc4cb5f64 (meep)
- 66c3639c468c822a33c746065bcbbae698d5900d (mpb)
- 5738ebee1b5e50e8e876c103be7afc2ec4f4daf0 (guile-libctl)
- 196627c2757c6dd6d2ef792e69eb6a969728cecf (harminv)

I'm not sure how to proceed so I'll stop at this point (with freehdl not in) 
until the path is clear :)
