Hi! Thanks!
I realize that make describe will probably fail, but what if I use a ?=
to set some defaults? If the prog (apxs in this case) isn't found the
defaults will used, I guess? Will this be OK? :
BUILD_DEPENDS= ${APXS_SBIN}/apxs:${PORTSDIR}/${APACHE_PORT}
RUN_DEPENDS= ${APXS_HTTPD}:${PORTSDIR}/${APACHE_PORT}
...
userpath= "${PREFIX}/sbin ${PATH:S^:^ ^g}"
.for DIR in ${userpath}
.if exists (${DIR}/apxs)
__APXS_SBIN!= ${DIR}/apxs -q SBINDIR
__APXS_HTTPD!= ${DIR}/apxs -q TARGET
__APXS_LIBEXEC!= ${DIR}/apxs -q LIBEXECDIR
.endif
.endfor
APXS_SBIN?= ${PREFIX}/sbin
APXS_HTTPD?= ${APXS_SBIN}/sbin/httpd
APACHE_PORT?= www/apache13
PLIST_SUB?= APXS_LIBEXEC=libexec/apache
APACHE_PORT?= www/apache13 # keeps make clean from going berzerk
...
