It's my pty and I'll cry if I want to.
Setting up servers inside an etch chroot can lead to some interesting problems. The most recent problem for me happened when I tried to install the perl module IO::Tty. During the test I would keep getting the following error:
It turns out that this is due to the /dev directory not being configured correctly. The solution was not easy to find, so I shall post it here along with a link to the post that provided me with it, in the hopes that it will get bumped up the search listing.
The answer, well there are two.

Debian locales
Have you ever come across this error:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_GB:en",
LC_ALL = (unset),
LANG = "en_GB.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
It turns out that this can be easily solved in a couple of steps (on debian).- install the locales package:
apt-get install locales
- reconfigure your locale:
dpkg-reconfigure locales
