Using Ubuntu 12.04
Package openvpn (1.0.1-4ubuntu5)
There is no .cnf file for the 1.0.1 version of the software.
The problem is the openvpn package needs a openssl.cnf file for the correct version of openssl which is 1.0.1.
As it does not have one, it defaults to openssl.cnf which does not exist.
Creating a link openssl.cnf >> openssl-1.0.0.cnf seems to solve the problem.
source ./vars indicates the file is missing
I created a link named openssl.cnf >> openssl-1.0.0.cnf which seems to solve the problem
