I suppose you don't need to go that far since the do-extract target
will remove the ${WRKDIR} extirely before extracting a tarball.

<quote source="bsd.port.mk">
# Extract

.if !target(do-extract)
do-extract:
        @${RM} -rf ${WRKDIR}
        @${MKDIR} ${WRKDIR}
        @for file in ${EXTRACT_ONLY}; do \
                if ! (cd ${WRKDIR} && ${EXTRACT_CMD} ${EXTRACT_BEFORE_ARGS} ${_DISTDIR}/$$file ${EXTRACT_AFTER_ARGS});\
</quote>

Which means ${WRKDIR} will be ${RM} -rf'ed if ${EXTRACT_COOKIE} does
not exist. :)
