Connect to the server and get the latest vasp.4.X.X.tar.gz file. Uncompress the *.Z of *.gz files using uncompress or gunzip. Untar the vasp.*.tar file using
tar -xvf vasp.X.X.X.tarMind: Make sure that you have removed or renamed the old vasp.4.X directory. Unpacking the latest version into an existing vasp.4.x directory will usually cause problems during compilation. Then proceed as described above.
