How to through DA: DNS, Install iconv(), ImageMagick for FreeBSD 5.2.1

Hi! does any body knows how to help me with it? any help will be really appreciable .....

1. need to install iconv()
2. need to install ImageMagick
3.still don't understand DA DNS with new domain registrant and switch from CPanel to DA:
a) I've my_domain.com and it hasn't placed on any host. But it has :
ns1.my_domain.com IN registrant_dns.com ( 1st net Ñ class)
ns2.my_domain.com IN registrant_dns.com ( 2nd net Ñ class)
------------------------------
i placed info about my host and NS to :
b) registrant_dns.com :

servername.my_domain.com A IP (for e.x. 65.100.0.10)
ns1.my_domain.com A IP (for e.x. 65.100.0.10)
ns2.my_domain.com A IP (for e.x. 65.100.0.10)
c) to my host and made :

servername.my_domain.com A IP (for e.x. 65.100.0.10)
ns1.my_domain.com A IP (for e.x. 65.100.0.10)
ns2.my_domain.com A IP (for e.x. 65.100.0.10)

and give to customers my NS (ns1.my_domain.com and ns2.my_domain.com)

So, will it be works or i'm mistaken?

customer_domain NS ns1.my_domain.com
customer_domain NS ns1.my_domain.com
customer_domain A IP (for e.x. 65.200.0.0)

Trying to help with a DNS setup is just guesswork unless you tell us the real domain names involved.
