you cannot run the qt in a vps like that.
you want to follow these instructions::
https://github.com/cryptogenicbonds/CryptoBullion-CBX/blob/master/doc/build-unix.mdwhich will produce something along the lines of 'cryptobulliond' in the folder /src (sorry didnt look at the makefile to double check names)
to list available rpc calls with the daemon started
should list all available calls
the easiest way would be to dump your private key then import to the new wallet install... this should be something like
./cryptobulliond importprivkey yourkey
