An error was found in the Wilson coefficients of the spin-2 gluonic condensate of dimension 4. Namely, the coefficients of the non-logarithmic terms proportional to [Formula presented] in the light quark limit of the heavy quark OPE, [Formula presented], are incorrect in the original version of the letter. Therefore, Eqs. (40) and (41) should be corrected to [Formula presented] where only the second terms of both equations are modified from the original expressions. The final results related to the same operator [Eqs. (47) and (48)] should thus be changed as follows, [Formula presented] Here again, only the second terms of each equation are modified. All other equations, discussions and conclusions of the letter are unchanged.
