MRTG on FreeBSD

hello

after portupgrading my mrtg, I'm getting this error:
-su-2.05b# mrtg
MRTG_lib version 2.100015 required--this is only version 2.100001 at /usr/local/lib/perl5/5.8.6/Exporter/Heavy.pm line 121.
BEGIN failed--compilation aborted at /usr/local/bin/mrtg line 84.
any suggestion on how to fix it?


some information that may be useful:
-su-2.05b# locate MRTG_lib
/usr/lib/mrtg2/MRTG_lib.pm
/usr/local/lib/mrtg2/MRTG_lib.pm
/usr/local/lib/perl5/site_perl/5.8.6/MRTG_lib.pm
-su-2.05b# perl -v

This is perl, v5.8.6 built for i386-freebsd-64int
