hi~~ nagios监控sql server服务，我在nagios Exchange下载了check_mssql_monitor的perl脚本进行监控，可是执行的时候报错——“BEGIN failed--compilation aborted at ./check_mssql_monitor line 32.” 32行报错，由于小弟是个新手，请各位帮忙看下32行错在哪里了...... 谢谢了

下边的红色字体为32行

#! /usr/bin/perl -w
#
# check_mssql_monitor  -  Return cpu workload from sp_monitor procedure of a SQL Server
#
# This script requires the FreeTDS library and DBD::Sybase Perl
# module. The SYBASE environment variable also needs to be defined.
# Make sure FreeTDS is compiled with --with-tdsver=8.0 !!!
#
# It also requires File:::Basename, Nagios:lugins and Time::HiRes.
