>Description:
mail/postfix/options.mk contains:
.if !empty(PKG_OPTIONS:Mbdb)
.  include "../../mk/bdb.buildlink3.mk"
CCARGS+=        -DHAS_DB
AUXLIBS+=       ${BUILDLINK_LDFLAGS.${BDB_TYPE}} ${BDB_LIBS}
.endif

BDB_TYPE on my system is db2.
However, BUILDLINK_LDFLAGS.db2 and BDB_LIBS are both empty, so later on linking 
fails:
Unresolved:
db_version
db_open

When manually adding -ldb2 things work. Why are BUILDLINK_LDFLAGS.db2 and 
BDB_LIBS not set correctly?
