LinuxQuestions.org - Problems locating CPAN.pm Fedora 10

hey, I have been trying to install some perl modules from CPAN but I am still stuck(todays my day 2). Maybe my CPAN module isnt working or whatever I said is so wrong. please give me some advice on this.I am so lost and I am a SUPER LINUX NOOB!

[PROBLEM]
this is my recent error report when i typed (trying to install catalyst manual):

Code:

perl Makefile.PL

output :

Code:

Subroutine author_requires redefined at inc/Module/Install/AuthorRequires.pm line 14.

Cannot determine perl version info from ./lib/Catalyst/Manual.pm

*** Module::AutoInstall version 1.03

*** Checking for Perl dependencies...

Can't locate CPAN.pm in @INC (@INC contains: inc /usr/lib/perl5/5.10.0/i386-linux-thread-multi /usr/lib/perl5/5.10.0 /usr/local/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi /usr/local/lib/perl5/site_perl/5.10.0 /usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.10.0 /usr/lib/perl5/vendor_perl /usr/local/lib/perl5/site_perl .) at inc/Module/AutoInstall.pm line 277.

And when I type

Code:

perl -MCPAN -e shell

output :

Code:

I have searched CPAN location in my computer using locate command but got none. do i have to reinstall perl? Please give me some idea on it.
