We present a new mechanism for gluino mass generation in models of dynamical supersymmetry breaking. The mechanism requires two colored chiral superfields which feel a nonabelian gauge interaction such that a fermion condensate is formed at a scale of order 1 TeV. Renormalizable hidden sector models, which typically yield unacceptably light gauginos, become viable if a gauge singlet is coupled to these chiral superfields. Moreover, the interactions of the gauge singlet with the Higgs superfields substitute the $\mu$-term. Visible sector models can also incorporate this mechanism; however, the models of dynamical supersymmetry breaking previously analyzed cannot be fitted in a simple visible sector model because they lead to vacuum expectation values for charged scalars.
