Subject: oil in UJoint boot

I *JUST* finished getting my motor back into the chassis. Pushed through the
front mount bolt when I thought about something. I noticed where I had taken
off the old ujoint boot between the rear main and the swingarm and realized
there was a small puddle of gear oil on the ground.

Is this acceptable or am I going to have to pull the motor back out and
replace a seal?
