I don't have it installed purely because this chroot is *just* for the

I'm leaning towards host-ncurses because it seems to be the cleaner way
to do it, but assuming that the host has it installed is probably a
fairly safe assumption.

Only issue is that some people might have a build server they upload the
config to, but even then installing ncurses-dev shouldn't really be a
big deal.

The offending tarballs have been moved out. I've checked them with file,
gzip and even opened them in file-roller and I can't see an issue. They
are up at http://nroach44.info/misc/br/ if you want to take a look.

I have a suspicion that they may have been redownloaded, but I'm not
sure if buildroot does wget -c or similar size checking logic by default.

A few days back when I was testing the autobuilder I was getting errors
on a mirror, from memory php's, so that might have something to do with
the issue.
