It seems that DSDP does not work with Apple's Accelerate framework, and hence if you use the +dsdp variant for py-cvxopt (not required), then you must use also use the +atlas variant for py-cvxopt. I suppose it is a bug that this conflict is not flagged in the py-cvxopt portfile. You could open a ticket for that part, if you like. In the meantime, just reinstall with consistent variants (I recommend using +atlas for all of the above, including numpy and scipy).
