It took me about a week to get openvpn going.

Echoing Stephen, have you done

modprobe tun

?

ethernet devices (eg eth0) aren't in /dev either

I have a binary (where it came from I don't know) called tunctl. From my notes I 
used it when messing around. It's not part of the scripts I use to invoke 
openvpnd

To scan server from client

nmap -sU -p 1194 50.55.x.x

#to turn on tun? device
# Set 'tun0' persistent and owned by uid 0
tunctl -u root -t tun0

#then when finished do
#Set 'tun0' nonpersistent
tunctl -d tun0
