vrotate() should do the trick:

vrotate(A,B)
Rotate A about origin by B. Given the x,y,z coordinates of a point in space
designated by the vector A, rotate that point about the origin by an amount
specified by the vector B. Rotate it about the x-axis by an angle specified in
degrees by the float value B.x. Similarly B.y and B.z specify the amount to
rotate in degrees about the y-axis and z-axis. The result is a vector containing
the new x,y,z coordinates of the point.

In your example, the new location can be found by calling vrotate(<0,0,-15000>,
<60,0,0>).
