you have a leak...use a product like SNOOP to apply to the entire breadth of the piping...at the joints to find your leaker~

Take a real good look at the front of compressor, the pulley and clutch with a bright light. A leaking compressor shaft seal can sling the oil and dye from the shaft seal without leaving much evidence.

...sadness if it is a shaft seal...

Shaft seals aren't too bad to replace if you have the tools and the time and the shaft and compressor are ok. Recover any R134a that's left, remove the compressor, remove the clutch and the pulley (field too if you feel the need), R&R the seal (use plenty of refrigerant oil or other suitable lubricant), evacuate and recharge the system Otherwise - yeah - not much fun to replace the compressor and orifice tube and flush the system (if the compressor goes to crap that is).
