Thank you for your response!

You were right, /bin/sh was the issue. I did some grepping and found Elixir was generating files that depend on /bin/sh. I am now able to build Elixir 1.9.2 on Guix.

I am attaching the patch to this e-mail. Please format/fix the code as necessary, I am not too familiar with Guile and other Scheme/Lisp languages.

I have locally fixed most of the issues related to this (I can now manually run the Makefile in the generated Guix folder without any tests failing), but I am stuck on a part where the tests spawn binaries and wait for a certain file to be created in a certain location. This does not work during the Guix build.
