SirDice of the FreeBSD forums suggested me to enter a PR for this. PROBLEM: Setting options on the ports' make build and make install command line -DWITH_SUEXEC as well as -DWITH=SUEXEC does not work. Neither does -DSUEXEC_DOCROOT=... -DSUEXEC_USERDIR=... -DSUEXEC_UIDMIN=... -DSUEXEC_GIDMIN=... -DSUEXEC_LOGFILE=... work. WORKAROUND: This all only works if one sets these defines in make.conf. EXPECTED BEHAVIOUR: Works like described in the documentation, using the make -D command line options.
