the --enablesnmpv3 directs that you want to use the Net::SNMP modules
instead of SNMP_Util.  The MRTG distribution does not include Net::SNMP.
You will have to load them separately (either form a package, or CPAN)

The version still needs to be specified on the host:
/path/to/cfgmaker --enablesnmpv3 --username=myusername
--authpassword=mypassword [EMAIL PROTECTED]:::::3

and to be clear, this would only work if the command line on IOS used to
generate the snmp user was something like:

snmp-server group mygroup auth
snmp-server user myuser mygroup auth md5 mypassword
