[CentOS] Samba/ldap install script from k12osn perl problems

There has been some very good work by a few people over in k12osn for 
setting up a SAMBA PDC/BDC environment.

Thing is their scripts are for Fedora core 3.

There are instructions on how to get things to go step by step instead 
of use the Fedora-based script, so I gave it a try.

Step 1 is to get apt running and everything current. I assumed yum would 
do instead.

step 2 has:

*Installing CPAN bundles

*

Now we need to make sure our perl modules are all there and up to date. 
We can do this easily by

Running

perl -MCPAN -e –shell

Let it run. Answer “no” when it asks about Manual configuration.

Once it stops you'll be at the cpan prompt....type

install Bundle::CPAN

this will install many perl modules for you. Answer “yes” to any 
dependency questions. When you get

to the question about “libnet”....answer “no”. Once you are 
finished...hit “enter” to exit....it'll run for a

few seconds more and then bring you back to the cpan prompt. For good 
measure let's type

install Net::LDAP (it should be up to date)

=======================================
Well I had many messages from the perl -MCPAN and install Bundle::CPAN 
and the install Net::LDAP just failed.

Being how this is rather foreign to me, how do I figure out what really 
went wrong and how to get it right?
