in reply to Net::IRC does not connect

(I didn't have problem when I installed it from CPAN)

That's because none of the tests failed. Since about 30-50% of all distros on CPAN have, as their complete test suite, a file that basically goes: 

use Test::More 'no_plan';

use_ok( My::Module );
isa_ok( My::Module->new, 'My::Module' );

That doesn't really test much, does it?

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
