@Anonymous Monk: Why am I getting permission denied error? I am the only user on this system, with admin rights. If I remember correctly I have installed, few modules before, like this, and never encountered permission denied problem.

@farang: Thanks, I never knew, about installing perl modules, your way.

Thanks, for looking into this, I could use Goo::Canvas in my Perl code now.

Figure it out

mkdir '/usr/local/man/man3' or die Fudge();
use Errno;
sub Fudge {
  my @r;
  while( my($k,$v)=each %!){
    $v and push @r, $k
  }
  join qq/\n/,
    int($!).q/ /.$!,
    int($^E).q/ /.$^E,
    @r, q/ /
}

Sorry, but I am beginner.

~/Documents$ mkdir delete
/usr/local/man$ mkdir deleteme
mkdir: cannot create directory `deleteme': Permission denied

After that I realized that it must be something related to sudo: Thanks for making me realizing that.

So, should I always use? : sudo perl -MCPAN -e shell or sudo apt-get install libgoo-canvas-perl

As farang, said, there is risk of messing with System perl
