Here is how I temporarily replaced a 5pf cap in one my TVs:
Four 22pf caps in series gave me about 5.5pf. Not beautiful, but it worked fine.
Basically, wiring two of the same caps in parallel doubles their capacitance, and wiring them in series divides it in half. (That's the "shade tree mechanic" version of the formula, anyhow.) If you have lots of caps lying around, maybe you can come up with something that works for the time being.
