Getting /dev/pts to work during installation?

While distrobuilder is running, error messages like this appear at various times:

Preconfiguring packages ...
E: Can not write log (Is /dev/pts mounted?) - posix_openpt (19: No such device)
(Reading database ... 11353 files and directories currently installed.)

Preconfiguring packages ...
E: Can not write log (Is /dev/pts mounted?) - posix_openpt (19: No such device)

After this operation, 4,347 kB disk space will be freed.
E: Can not write log (Is /dev/pts mounted?) - posix_openpt (19: No such device)

Are there any “tricks” that can be applied to the distrobuilder chroot so that /dev/pts exists (or whatever the underlaying problem is) to avoid these errors?
