problem building sendmail+sasl

[Robert Huff]

	I'm trying to add SASL to sendmail (more accurately, to make it
so it's done as part of the default sendmail build under -CURRENT).
	I have:

	1) installed cyrus-sasl-2.1.20_1
	2) added

SENDMAIL_CFLAGS=-I/usr/local/include/sasl -DSASL=2
SENDMAIL_LDFLAGS=-L/usr/local/lib
SENDMAIL_LDADD=-lsasl2

	to /etc/make,conf
	However, when I buildworld I get:

/usr/src/lib/libmilter/../../contrib/sendmail/src/sendmail.h:134:25: sasl/sasl.h: No such file or directory
/usr/src/lib/libmilter/../../contrib/sendmail/src/sendmail.h:135:29: sasl/saslutil.h: No such file or directory
In file included from /usr/src/lib/libmilter/../../contrib/sendmail/libmilter/sm_gethost.c:14:

/usr/src/lib/libmilter/../../contrib/sendmail/src/sendmail.h:135:29: sasl/saslutil.h: No such file or directory
mkdep: compile failed
*** Error code 1


	What have I overlooked?
