OpenVPN Install Failure

[skimpniff]

Hey guys,

I am running into an issue with getting openvpn-openssl installed on my old mk iv. I just got the nano and want to repurpose my mk iv to be an openvpn client (episode 2018). The old package path in the opkg.conf file is 404. So I rummaged around the internets for a while and found the openwrt path with openvpn in it (http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/packages/base/) but when I install I get a 127 error:

Configuring openssl-util.
//usr/lib/opkg/info/openssl-util.postinst: line 4: default_postinst: not found
Configuring liblzo.
//usr/lib/opkg/info/liblzo.postinst: line 4: default_postinst: not found

Configuring openvpn-easy-rsa.

Collected errors:
 * pkg_run_script: package "openssl-util" postinst script returned status 127.
 * opkg_configure: openssl-util.postinst returned 127.
 * pkg_run_script: package "liblzo" postinst script returned status 127.
 * opkg_configure: liblzo.postinst returned 127.

 * pkg_run_script: package "openvpn-easy-rsa" postinst script returned status 127.
 * opkg_configure: openvpn-easy-rsa.postinst returned 127.

Do you have any advice or an old mirror or something so I can get this bad boy up and running? The old threads form 2012 have 404 pages as well.

Thanks in advance.
