[Samba] Idealx script prerequisites?

[Alex Harris]

    I'm trying to setup a PDC (and later on a BDC as well) using samba 
3.02a and openLDAP 2.2.13 and I'm having some trouble with the idealx 
scripts. When I run the command /usr/local/sbin/smbldap-useradd alex I 
get the message:

Can't locate object method "new" via package "Net::LDAP" (perhaps you 
forgot to load "Net::LDAP"?) at /usr/local/sbin//smbldap_tools.pm line 176.

What does this mean? Presumably it's looking for some perl module that 
isn't installed, but I have no idea which one, or how to install it. Let 
me know if there's any other information that might be pertinent, 
thanks. :-)
