If it's not coming from the drip pan, chances are it's compressor oil. You probably will not want to run it until you can fix the leak and replace the oil that's leaked out. running it without oil will kill it.
Your two choices would be to call a repair person, or to look up how (and if) you can seal the leak and change the oil yourself.
I called a repair person, but I need to wait for 3 days until they can get me in.
Could the oil get to the front of the fridge if the compressor is located in the back? I checked around the compressor itself but didn't see any leakage.
If it's leaking onto the metal framework it can pool in there and come out wherever it finds a hole or low spot to come out. It's really hard to say for sure without getting under there and seeing what's going on.
