thank you for your answer.
I will try in this way on Monday.
Please, let me understand how CPAN extactly works.
If I try: 
get Module

[download]

My module is downloaded in some directory.
where?
In my case is: /home/myUser/.cpan/build

Is there any way to download the module in a different directory? Then: 
test module

[download]
It do the tests.
Where are located the test?
I think in the directory .cpan/build/module/t


finally: 
install module.

[download]
The module is installed in Perl directory, which maybe different from CPAN downloaded module.

Also here: is there any way to install in a different directory?

Is it correct?

Finally: if I want to do some changes to Makefile.PL, in order to pass the tests suite,
is there some way to do it in a "clean" mode?

Please, if you have that possibility, can you go into these aspects thoroughly?

Thank you very much for your answer.
