Running 3.1.

I curious why postfix will not compile with pcre-6.7.

PCRE-6.7 is installed:

  #: pkg_info pcre                            
  Information for pcre-6.7:

Yet make in pkgsrc/mail/postfix-current produces -DNO_PCRE?

   cc -DDEF_QUEUE_DIR=\"/var/spool/postfix\" -DDEF_DAEMON_DIR=\"/usr/pkg/libexec/postfix\"  \
	 -DDEF_COMMAND_DIR=\"/usr/pkg/sbin\" -DDEF_CONFIG_DIR=\"/usr/pkg/etc/postfix\"          \
	 -DDEF_SENDMAIL_PATH=\"/usr/pkg/sbin/sendmail\" -DDEF_MAILQ_PATH=\"/usr/pkg/bin/mailq\" \

	 -DDEF_SAMPLE_DIR=\"/usr/pkg/share/examples/postfix\"                                   \
	 -DDEF_README_DIR=\"/usr/pkg/share/doc/postfix\" -DHAS_DB                               \
	 -DNO_PCRE                                                                              \ <<<
	 -DSNAPSHOT -O2 -I/usr/include -I. -I../../include -DNETBSD3 -o flush flush.o           \
	 ../../lib/libmaster.a ../../lib/libglobal.a ../../lib/libutil.a -L /usr/lib            \
	 -Wl,-R/usr/lib -Wl,-R/usr/pkg/lib

Where did I go wrong?

TIA,
