I've add "/var/tmp" into the chroot directories inside nix/libstore/build.cc with the attached patch (based on v0.14.0 tag) and the installation of gettext and the other dependencies not yet installed seem to finished correctly.


Is there someone who could validate than this patch is correct and is the correct way to solve this problem before i try to submit my the patch mailing list ? :)


Thanks,


Best regards,
