If I don't explicitly set $HOME, the build fails with

Debugger entered--Lisp error: (file-missing "Setting current directory" "No 
such file or directory" "/homeless-shelter/")
  call-process("sh" nil t nil "-c" "evince --help")

I tried adding the following to the arguments list:

#:tests? #t
#:test-command '("make" "test")

and the build now fails with this error:


starting phase `check'

I hunted around emacs-xyz.scm and tried using ert-runner, which
complained that the tests are in the wrong directory, since it expects
apparently the tests to be under test/ and not tests/, as in the case of
latex-extra.  Still, by looking at how the test target is defined in the
Makefile of latex-extra, I think that this is not the problem.  On the
other hand, I don't believe that package cl being deprecated is the
problem either, since that is normally a warning and not an error.

Do you have any ideas as to how to debug this kind of issues?

FWIW, I am already using the draft version of this package out of my
private channel, and it works nicely, so this problem seems to be
specific for the tests.

I changed this to propagated-inputs.

Fixed.

Fixed as well.
