When the engine is cold, the oil may well be below the end of the dipstick. Your dry sump system has to be really low before you lose oil pressure, although the SE seems to shift funny even if a little low. You may not be low at all, however. You won't know until you bring the Spyder to full operating temperature. When was the last time you checked the oil? How much oil was on the floor? A little oil makes a huge spot. A few drips isn't a sign of disaster.
Possible sources of the oil.....
Drips from spilled oil left from changing the oil.
Drips from oil in the airbox.
Oil/Water from a water pump shaft leak.
Leak at an engine gasket.
Drips from the coolant overflow or emissions vent that look like oil but are not.
If it were me, I'd start it, ride it (if there was no warning light) until it got up to operating temperature for at least ten minutes, then check the oil by the procedure in your manual (full operating temp, run for 30 seconds to evacuate sump, check within about a minute, screw in dipstick all the way). If it is at the proper level, you are good to ride to the dealer or elsewhere. If it is low, add enough to get it to the proper level and ride it. Towing it in for a few drips on the floor is overkill.
