locale problem when setting up a chroot using debootstrap

[andy baxter <andy@earthsong.free-online.co.uk>]

I'm setting up a chroot using debootstrap, eventually for use with user 
mode linux. I have got it mostly working ok, but when I install some 
packages (e.g. mc), there are a load of errors which seem to be to do 
with locales. Perl (I think) is saying something like check that the 
right locale is installed for the language code you have configured 
(en-GB). (Its hard at the moment to give the exact error message because 
it's on another machine and that filesystem has just died so I'll have 
to rebuild it before I can reproduce the error). Is there some package I 
need to install inside the chroot?

Thanks,
