I am trying to install iRedMail which has a dependency on SOGo and thus SOPE however receiving below error.
Your kind advice is greatly appreciated.

cat /var/db/ports/devel_sope2/options OPTIONS_FILE_SET+=LDAP

OPTIONS_FILE_SET+=MEMCACHED OPTIONS_FILE_SET+=MYSQL
OPTIONS_FILE_UNSET+=PGSQL

cd /usr/ports/devel/sope2

make install clean
