Hi,

I think the easiest way how to get working dhcp-4.1.x on RHEL-5 is to 
recompile my source rpm [1]:

- download http://jpopelka.fedorapeople.org/dhcp-4.1.2-5.ESV.R3.el5.src.rpm
- yum install rpm-build
- rpmbuild --rebuild dhcp-4.1.2-5.ESV.R3.el5.src.rpm
- install RPMs from /usr/src/redhat/RPMS/<arch>/

Then you would probably need to:
- allow dhcpv6 ports in firewall, i.e. 546 for client and 547 for 
server. For testing purposes you could also turn whole firewall off with 
'service ip6tables stop'
- Do what Scott already suggested, i.e.
   - switch SELinux to permissive mode (as already suggested)
   - specify interface when running dhclient
