Wise fathers-of-wisdom,

I have problems involving configuration of a perl package.
The perl package hooks into the ExtUtils::MakeMaker
CONFIGURE hook to ask for package-wide settings when
running perl Makefile.PL.
These settings are written to a Config/Default.pm file.
The idea is that when you give no config file in the
constructor, it will fetch it from the default file.
For this to happen I just construct the Default.pm file
and the perl install mechanism will do the rest.

Now, I also want to do the following:

1. I want to make a My::Module::Config::save_config method
2. I want to have a perl -MMy::Module::Config -e setup

Basically I've two questions to be solved:
First, how can I save the Default.pm in the installed (site) perl module tree,
i.e. after running make install?
Secondly, how can I use the My::Module::Config module
in the Makefile.PL when the Makefile.PL resides in the /My/ directory?

Somebody any idea please???
