You should use a pipe of cat and tar commands.  There are install.sh
scripts, which know how to install files from the distribution.

if [ "$1" = "all" ]; then
	dists="base bin contrib etc games gnu include lib libexec release sbin share sys tools ubin usbin"
else
	dists="$*"
fi

echo "Extracting sources into ${DESTDIR}/usr/src..."
for i in $dists; do
	echo "  Extracting source component: $i"
	cat s${i}.?? | tar --unlink -xpzf - -C ${DESTDIR}/usr/src
done
