Hi everyone! Another silly question.

I am trying to build some python package, I imported the definition from pypi (using guix import pypi -r ... (so a lot of packages) and then started to debug and fix some stuff.

All the python packages are built using (build-system python-build-system)

But, there is one package in the list that in its tests is using some environment variables, and the test (and the built) fails, since the variable (LANG in this case) is not found at built time. The variable is obviously set, so I was wondering if guix is removing all the variables when building ... (seems like it).

Any advice about how to deal with this?
