Sounds like it's most probably the front crank seal. Wipe everything clean then look again after an hour or two of driving. If you don't see the source after looking all the places listed above it's probably the front crank seal. By the way, if it's your vacuum pump that is leaking it's time to change it. Come to think of it, even if it isn't leaking and it's the old style pump without the bolt heads on the front, it's still time to change it.
