How can i start just one program of the suite?

if i only want to draw sth or write a short letter I don’t need the whole suite - and don’t want to wait, until the whole suite started. (MacOSX 10.6.8, LibreOffice

To my knowledge, each component of the suite require several other elements of the suite because of the way things are organized. For example, no matter what you use, Calc, Draw, Impress, or Writer, all of them need soffice.bin (in Linux) to run.
