Hi, welcome to Pardus.
I've whacked together a quick pisi file of openvpn 2.1_rc10, keep in mind though it's an unofficial build. I don't know anything about the program itself so I haven't tested it but it does build and install cleanly. It's basically an alternative for if you can't get it built successfully or can't wait until the official repo is updated (likely to be after the next stable release of openvpn).
If you'd prefer or have any problems, I'm happy to post the steps taken in creating it.
To install (as root):
pisi it openvpn-2.1_rc10-5.pisihttp://www.box.net/shared/iyn1p9dfij
Note for noscript users: First time I've used box.net for file hosting, seems like you need to allow box.net and boxcdn.net. It seems slightly more reputable than sites like rapidshare but that's all I know about it.
