Nope, but I have a good guess.

You've got 2 versions of BER.pm and possibly some of the other
perl modules involved in MRTG.  Your Perl 5.6.1 either included
a BER.pm that was dumped in /usr/local/lib/perl/modules/ (or
some place similar).  My guess is that they're different versions.
Search for dupes of the stuff in .../mrtg/lib/mrtg-2/*.pm

Disclaimer:  This is only a guess.

If you get really stuck, there are some marginally documented
debug options in the mrtg perl script.  Near the top, you'll find:

# cfg  - watch the config file reading
# dir  - directory mangeling
# base - basic program flow
# tarp - target parser
# snpo - snmp polling
# fork - forking view
# time - some timing info
# log  - logging of data via rateup or rrdtool

Change the first line to whatever debug level looks interesting
as in:

Do NOT try to do debugging with:
  RunAsDaemon: Yes
as it sends the output to an unattached terminal (or /dev/null).
