The Debian unstable version imposes this dependency. I compiled proper Debian packages on Dapper using the lyx developers Debian script without issue so I suspect the dependency is too strict but hey I am not privy to the Debian lyx maintainers logic. I can lodge a complaint on the Debian maintainers mail list if you wish, they seem to like Ubuntu ;-)
