freebsd我安装ezmlm的时候出现下面的错误，我改怎么处理？

fantasys

tp# make setup
./load ezmlm-gate subdb.a getconf.o slurpclose.o slurp.o getopt.a getln.a auto_bin.o env.a sig.a fs.a strerr.a substdio.a stralloc.a alloc.a error.a str.a case.a wait.a open.a lock.a seek.a `head -1 conf-sqlld`
/usr/bin/ld: cannot find -lnsl
*** Error code 1

Stop in /usr/local/src/ezmlm/ezmlm-0.53.


我安下面的安装的，qmail我一经安装好了

1、 安装ezmlm

#cd /down
#tar zxvf ezmlm-0.53.tar.gz
#cd ezmlm-0.53
#make
#make man
#make setup


2、 加入ezmlm的mysql支持的方法
A：创建ezmlm数据库

#/usr/local/mysql/bin/mysql -u root ?p
mysql>;create database ezmlm;?


B: 设置ezmlm加入mysql支持

# tar -zxvf ezmlm-0.53.tar.gz
# tar -zxvf ezmlm-idx-0.40.tar.gz
# mv ezmlm-idx-0.40/* ezmlm-0.53/
# cd ezmlm-0.53
# patch < idx.patch
# cd sub_mysql
# ee sub_mysql/conf_sqlcc
-I/usr/local/mysql/include/mysql

# ee sub_mysql/conf_sqld
-L/usr/local/mysql/lib/mysql -lmysqlclient -lnsl -lm ?lz
#cd ..?
# make mysql
# make clean
# make man
# make ch_GB
# make setup?

呃，为什么不用 ports 呢？ (/usr/ports/mail/ezmlm-idx)
