[mrtg] perl taint mode (Insecute dependency in kill )

[Leonardo Reginin]

Hi fellows.

I'm getting this error message after I upgraded MRTG and Perl version. 
The MRTG CFG in use have RunAsDaemon: Yes

Insecure dependency in kill while running with -T switch at 
/usr/local/lib/perl5/site_perl/5.8.9/MRTG_lib.pm line 1180, <READPID> 
line 1.

I googled a lot but I could not find anything relevant. I would 
appreciate any help.

The environment is:

#uname -v
FreeBSD 7.3-RELEASE #2: Wed Apr  7 10:49:49 BRT 2010     
root at mrtg:/usr/obj/usr/src/sys/GENERIC
#perl -v

This is perl, v5.8.9 built for i386-freebsd-64int
(with 1 registered patch, see perl -V for more detail)
