I am trying to package the Standard ML of New Jersey (SML/NJ) compiler
in Guix. My current understanding is that its installation process
relies on the existence of /bin/sh in a fundamental way. Is there a way
to add /bin/sh to the build environment?
In the build phase of the package definition, I tried something like
this:
(mkdir-p "/bin")
(symlink (which "sh") "/bin/sh")
However, `mkdir-p` always fails with:
ice-9/boot-9.scm:1669:16: In procedure raise-exception:
In procedure mkdir: Permission denied
