Using 'export -f FUNCTION' from within a script doesn't work

Question

Why doesn't the 'export -f FUNCTION' work as expected in the following:
#!/bin/bash
target="$1"
[[ -z "$target" ]] && echo "No target specified." && exit 1
work() {
bsdtar -xOf "$target" .PKGINFO | egrep -w 'pkgname|arch|pkgdesc|group|conflict|depend|replaces' | sed -e 's/pkgname/\npkgname/' >> /scratch/pkgs.log
export -f work
find /scratch/repo -name "$target*.pkg.tar.xz" | parallel work
It errors out when called:
% ~/bin/repo/check_pkgs broadcom

That was a copy/paste error based on me trying multiple scripts.  Sorry about the confusion.
% ./test linux
zsh:1: command not found: work
zsh:1: command not found: work

It's also the wrong solution to be exporting functions...
Yay for ineffective crossposting... https://bbs.archlinux.org/viewtopic.php?id=153461
Exporting functions is recommended in the parallel man page.
The command must be an executable, a script, a composed command, or a function. If it is a function you need to export -f the function first. An alias will, however, not work (see why http://www.perlmonks.org/index.pl?node_id=484296).
Also, how is this a cross post?  The post you referenced is about parsing input, this one is about calling a function from within the parent script.

No idea
