I used:

    sudo "/Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia" --volume /Volumes/Mavericks/ --applicationpath "/Applications/Install OS X Mavericks.app"

Note the double hyphens before the keywords. The quotes just make it easier to read.

Good catch! I think it tried to format my double hyphens as a dash. Should've thrown it in a code tag.
