Sorry, I didn't fully explain. I meant that instead of doing this
module-ref expression to include "gcc-toolchain", I simply included
"gcc" (which is already imported in lisp.scm) in the propagated-inputs
and it worked fine (in a pure container) for both the "jpm install" and
the "jpm build" command.

So you think the following would make sense as a sane default for the
"SSL_CERT_DIR" env variables as an example?

#+begin_src scheme
 (native-search-paths
   (list (search-path-specification
          (variable "SSL_CERT_DIR")
          (files (list "/etc/ssl/certs/")))))
#+end_src

I'm not sure what would be a good default for "SSL_CERT_FILE" though.

Thanks,
Omar
