So that the software would "just work" as required, without the
need for any run-time MIB configuration.

(And it was your configure incantation that I was commenting on.
So why *did* you want to set that at configure time? :-))

Yes - that should also amend the list of default MIB modules.
Basically, there are several places this information gets set:

  -  command-line options   -   -m  and  MIB::object
  -  snmp.conf file(s)   -  "mibs"
  -  code files   -   config_add_mib()
  -  configure  -   --with-mibs
  -  hardcoded default

In each case, the earlier settings in this list amend (or overwrite)
the later ones.   So if the code was compiled using
    --with-mibs=+DELL-CMC-MIB
then you don't need to specify this in an snmp.conf file,
or on the command line.

Yes - every app should look at snmp.conf.
If that doesn't seem to be happening, then try running with
   -Dread_config
which will report which config files are being read in,
and what they contain.
