Hi,

Can you check in the build log of 6kj7f8kz3h5fizir8l7nrxgras2ns3ww-m4-1.4.16
what the line =E2=80=9Cchecking which shell to use for syscmd=E2=80=9D says=
?  (Remember
that build logs are kept in /nix/var/log/nix/drvs or similar, depending
on your localstatedir.  Make sure the value passed to --prefix in that
log matches the one above.)

Here it reads this:

  checking which shell to use for syscmd... /nix/store/ryk1ywzz31kp4biclxq3=
yq6hpjycalyy-bash-4.2/bin/sh

If it chose /bin/sh, then it means that you built M4 out of the chroot
(or with /bin in the chroot), but now you=E2=80=99re trying to use it withi=
n a
chroot.

Ludo=E2=80=99.
