i was just running this:
UnixBench should begin running tests and output a final score. For Debian/Ubuntu:

    # apt-get install libx11-dev libgl1-mesa-dev libxext-dev perl perl-modules make
    # wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.3.tgz
    # tar xvf unixbench-5.1.3.tgz
    # cd unixbench-5.1.3
    # ./Run
but it gave me this:
The hostname -f command returned: $1
