I believe this is a library specific thing. I don't think this should be
related to this patch.
Also, if you are running a guix shell with --pure flag, try adding
coreutils to your shell because jpm calls the "cp" command when building
libraries.
I tried with "jpm install -l spork" and with "jpm install -l sh" and it
works fine. I believe the --cc flag is meant to be used for the jpm build
command.
