Hi Nome

Thank you for your message.

You sent your email to all 3 bugs: address@hidden,
address@hidden, address@hidden. It is not a good
practise. Instead, it appears to me more appropriate to send to

First note that these are closed:

 - 22629 on Sep 2nd 2018
 - 32022 on Dec 17th 2018

so what they were proposing now exist in master, I bet. ;-)

Second, it will help to point exactly where Ludo posted what you are
referencing to. Because 22629, 26608 and 32022 are big threads. :-)

If you know more or less the date, you can find the commit. And *if*
this commit is after the big 0.15 overhaul, you can 1. Guix checkout
with "guix pull --commit=<hash>" then 2. Git checkout your guix clone
to this commit and 3. use "guix environment guix" to spawn an shell
with all the dependencies available. And the code you are referencing
should work.

Third, please describe what you are trying to achieve.

All the best,
