Oil on belts... [updated w/ pics], how bad is this? Options

[Abraxis64]

Okay, so i just recently changed my accessory belt b/c it had a small tear in it...ended up actually breaking the tensioner bolt so i had to get that replaced and stuff. so, anyway, the acc belt starts squealing like a banshee again and i'm wondering why, since it's brand new (i re-tensioned it after the first couple drives with the new belt, although it's all by feel since i don't have one of those guages the big book says to use).

anyway, i popped open the hood and i think i discovered why it's squealing--i've got oil splatter marks right in the area around where the belts/sproket is/are and a nice littel band of black on the underneath part of my hood. now, this looks like it's pretty bad, but what could have sprung a leak in this area? i'm not very familiar with toyota motors, as i've owned hondas all my life. perhaps it's just a minor gasket (what's in this area? starter? something else?). maybe i'll be able to get a pic or two up later...but does this problem sound familar to anyone?

thx in advance

edit: i realized it'd probably be helpful if i specified what type of engine this is--it's a 99gt liftback, autotragic, 2.2L

edit:
oil spray underneath hood
dirty communist oil invading my engine bay
oil splatter on pulley/sprocket thing
