Dear Daniel,

running faketime in a Jessie or Sid chroot on a Wheezy installation
fails as follows:

Initially observed a few days ago (hence reporting against 0.9.6-3 in
Jessie) on Wheezy/Sid amd64 inside a Jenkins job at
http://jenkins.grml.org/view/Debian/job/zsh-binaries/architecture=amd64/174/console
after this commit:

Severity set to important because this may affect the package when being
build on the build daemons as probably most of them run Debian Stable
kernels AFAIK. Feel free to raise or lower the severity if you think the
issue is more or less worse.

Marked as "affects zsh" because it causes FTBFS with the zsh package as
of the current pkg-zsh git HEAD on our jenkins.

If there's anything I can do to avoid this issue in the way the zsh
package uses faketime -- I'm happy about any hint.
