  We reanalyze precision LEP data and coupling constant unification in the
minimal supersymmetric $SU(5)$ model including the evolution of the gaugino
masses. We derive general bounds on the primordial gaugino
supersymmetry-breaking mass-scale $m_{1/2}$ in terms of the various input
parameters. The model cannot accommodate $m_{1/2}<1\TeV$ for values of $\as <
0.115$, even for extreme $1-\sigma$ values of the other inputs. We emphasize
the sensitivity of this type of calculations to the various input parameters.
