Misalignment Frustration - Mate Tolerance?

Is there a way to set a mate tolerence? I'm trying to mate two components but I get this sillly error:

"The components cannot be moved to a position which satisfies this mate. Planar face and line are not parallel. Angle is 0.00014834deg."

Suffice to say that manufacturing tolerences etc will not allow precision to the ten-thousandth of a degree...
