[hjl@gnu-64 sharable]$ cat /etc/zprofile
#
# /etc/zprofile and ~/.zprofile are run for login shells
#

# all bourne shells should source /etc/profile


PATH="$PATH:$HOME/bin"
export PATH
[hjl@gnu-64 sharable]$ rpm -qf /etc/zprofile
zsh-4.0.7-1

A better one should look like

[hjl@gnu applied]$ rpm -qf /etc/zprofile
zsh-4.2.0-3
[hjl@gnu applied]$ cat /etc/zprofile
#
# /etc/zprofile and ~/.zprofile are run for login shells
#

PATH="$PATH:$HOME/bin"
export PATH

# source profile
if [ -f /etc/profile ]; then
        source /etc/profile
fi
