	package_url="https://packages.macports.org/$1/"

	then print-field 'Binary Package' "$package_url"
	else print-field 'Binary Package' no
	fi

This only checks the existence of the folder, not the exact version of the package. Need to get the package version and OS version.

Package version can come from the command, or another invocation of

port info --epoch --version --revision $package

Note that the invocation takes about a second. OS version can come from $OSTYPE (Bash one is different from Zsh one), or uname -r:

shopt -s extglob
os_version=$(uname -r)
echo ${ver%%+(.+([[:digit:]]))}

See shell parameter expansion and pattern matching in Bash manual. Another option is to use a proper scripting language.
