This has been answered many times on various mailing lists already.
There have been 8 different FC4 tzdata updates released that have uptodate
America/Los_Angeles timezone data (2005m-1.fc4 and up), so unless you never
ran yum update, you surely had it installed already.  Even if there were
none, you jus can install fc6 or rawhide tzdata, it will install on FC4 just
fine, you don't need to bother rebuilding it.  You haven't said how it
failed, it certainly builds here even for RHEL3 which is much older.

All you need to do in FC4 is rerun system-config-date, because FC4
glibc-common didn't have /usr/sbin/tzdata-update %trigger on tzdata.
Or run
. /etc/sysconfig/clock
cp /usr/share/zoneinfo/$ZONE /etc/localtime
