However if you still want to use it.
First you need to update your vps then install bitcoind
apt-get update
apt-get install bitcoind bitcoin-qt <- This will install and setup bitcoind
then start bitcoind (or run bitcoin-qt until the block chain is complete, and then run the bitcoind once you close bitcoin-qt)
Once you start it type ./bitcoind getinfo and should get a response.
Then run this
bitcoind -rpcuser=testuser -rpcpassword=testpass -debug
( this sets the username and password that is allowed to connect to bitcoind)
------------------------
Then Follow step 2 instructions
Ps: I have never installed Bitcoind on a vps before,i just posted whatever was in article with some extra info.
I'm not sure but you might need to create a .conf file
