  The normal phase of the high-$T_c$ cuprates is apparently not described by
Fermi liquid theory. It has been proposed that a dynamically generated gauge
field must appear in the effective field theory. Even a simple spinon-gauge
system is complicated, becoming strongly coupled at low energy. We show that in
a large-$n$ approximation the theory can be solved and has a nontrivial fixed
point. Also, we find that there is no antiferromagnetic instability at weak
coupling.
