>Description:
noticed a useless cat(1) in install.sh for ports:

- cat ports.tgz | tar --unlink -xpzf - -C ${DESTDIR}/usr
+ tar --unlink -xpzf ports.tgz -C ${DESTDIR}/usr

this works well for bsdtar.
>How-To-Repeat:
it works even without cat:

        # setenv DESTDIR /
        # tar --unlink -xpzf ports.tgz -C ${DESTDIR}/usr
        # echo $?
        0

>Fix:
remove cat(1) from install.sh
