It looks like you haven't run tools/parse_olson to generate the time
zone modules yet.

This script needs the Olson database files to run, which can be found
at ftp://elsie.nci.nih.gov/pub/ in a file called tzdata*.tar.gz.

Once you've run this script you will be able to test and install this
distribution.
