I thought my problem solved... but it wasn't.

When I try to install other Module which needs MakeMaker, say WWW-Mechanize-Firefox, and type command "cpan WWW::Mechanize::Firefox", then modules which needs MakeMaker doesn't use newly installed MakeMaker-6.63_02 but they require 6.62 and begin to download and try to use 6.62.

They don't use most recent version of locally installed MakeMaker... Again I am stacked and these are what I've done so far.

Q. fetch module with "cpan -g" and why not install it manually?
A. this works. Modules uses MakeMaker-6.63_02. And I thought, do I always have to do this?

Q. change "prerequisites_policy" of MyConfig from "follow" to "ask". Answer No to MakeMaker.
A. This is best solution so far(for me). It becomes hard when many modules need MakeMaker(like WWW::Mechanize::Firefox). I wonder there is an option like "most_recent_in_local".

Q. how about using "distroprefs"?
A. I found many examples in CPAN.pm's source directory. I tried like this one.

---
match:
  distribution: ".*"
depends:
  configure_requires:
    ExtUtils::MakeMaker: 6.63_02
  build_requires:
    ExtUtils::MakeMaker: 6.63_02
  requires:
    ExtUtils::MakeMaker: 6.63_02
[download]

it changes cpan's output. but it seems not working as I expeced.

Distropref is somewhat difficult for me. I am thinking this is the place to change, but I thought it is better to ask monks for wisdom.

My question in a line:How can I tell cpan not to use MakeMaker 6.62 but locally installed 6.63_02?
