could not find /usr/local/timezone

Folks,

This is a new one on me, but possibly because it's my first time working on
Gentoo:

Version: 8.0b4
Platform: Gentoo Linux 2.6.8
Severity: Unknown
Message:
LOG:  could not open directory "/usr/share/timezone": No such file or
directory

What's it mean?  Am I missing a package?
