By default GNU getopt is not installed on BSDs.

In Mac OS X is /opt/local/bin/getopt , 
in OpenBSD  is /usr/local/bin/gnugetopt , 
in FreeBSD  probably is /usr/local/bin/getopt , 
in NetBSD   is $somewhere/getopt

I don't know if this is acceptable, but we could use a function in makepkg
to find the *right* getopt, something like: 

for x in `echo $PATH | sed s@:@\ @g`; do 
    for y in getopt gnugetopt; do 
        if [[ -x $x/$y ]]; then 
            $x/$y --version 2>&1 | grep getopt &>/dev/null
            if [[ $? == 0 ]] && [[ -z $getopt ]]; then
echo $getopt

(It works because GNU getopt prints "getopt (enhanced) 1.1.4" and BSD
getopt prints "--")

Yeah, it's ugly.
