ipkg wouldn't cascade on installing openvpn, so I had to do through one by one to install. Then I got stuck on openssl-util when trying to install openvpn-easy-rsa.
I hate to post with no solution, but I'm a total newbie at OpenWRT and I'm short on spare time to troubleshoot.
root@OpenWrt:~# ipkg -V 3 install openssl-util_0.9.8e-1_mipsel.ipk
